TEAC A-4010SU Tape Recorder

 This one's a big SCOOOOORE!

Not only is it cleaner than expected, I met the original owner, who's the grandfather of the young guy who listed it. He bought it new, at the BX, while he was stationed in "Viet Nam" with the Army.

The heads show some wear, but it's what I consider "acceptable", and the tape path, pinch roller, and capstan are really clean. He said he took good care of it, and it shows. It's got some smudges on the front panels, but they're easy to clean with some of the stuff I used. The wood case is in amazing condition considering he had it so long, and it was shipped around while he was in the Army.

They gave me a head demagnetizer, and a bag of spare replacement parts, including a new pinch roller, capstan, and TWO complete sets of belts for it.

And the original manual, warranty card, and bag of accessories.

Even before the young guy brought the deck out, he said his Grandpa also had these two boxes of "Tapes and Stuff" that I could have if I wanted. Not having any tapes, or empty reels for that matter, I said sure, and we loaded those in the car.

WHATTA HAUL!

I was given Fifty-Six Ampex tapes with program material on them, Eight brand-new sealed-in-plastic tapes, Ampex 341 and Maxell Low Noise tapes, and Six brand-new empty take-up reels.

This is over $800 worth of free goodies, and I'm indebted to them.

 And one of the tapes is a live recording of a Bob Hope USO tour, two reels worth.

So I'm stoked about this, and will do a "Cleaning/Lubrication" check per the manual, and then see what's on some of these tapes. I don't need several reels of "Beer Barrel Polka" and several reels with "Sound of Music", "Sounds of Lerner and Lowe", and "The Music Man" on them. I'll check the tapes to see if the media matches what the box says, and run them through a bulk eraser.

Looks like I won't need to buy any recording tape for quite a while.....

Update On The Pioneer SX-780 and Speakers

 Sooooo....I dragged the two speakers I made some time ago out of the basement, and set them up with the SX-780. When I used these speakers before, I used them with my turntable, preamp, and a small, PylePRO PCA2 "40 Watt" amplifier. Hah....in your dreams, maybe. For one-half cycle at some given frequency. While cooled by LN2.....

The first no-no I did was to have the speakers about 18" from the turntable. Yes, I know better, but in my haste I used the model car workbench to set things up quickly, there wasn't much room, and I wasn't planning on listening at high volume.

Nope, doesn't work. Even at moderate volume, having the speakers that close to the turntable causes a form of audio feedback, where the sound pressure waves from the speakers vibrate the turntable at variable frequencies, which get picked up by the stylus,  fed to the amp, and then the speakers, and then the turntable again, and presto! TERRIBLE sound.

So I set the SX-780 on the den coffee table, set the speakers up a few feet away and 6' apart to see what kind of separation they have, connected things up, and brought the receiver up.

 

YOWIE-ZOWIE! This thing sounds GOOOOOD! I had a clip lead about 29" long (1/4-wavelength!) that I used for an antenna, and I could get just about every station on the dial. The stronger stations ("Full Quieting" in FM-Speak) sounded spectacular, WAY better than they do on our home theater system when I use the FM tuner. I knew this was a premium grade receiver when it was new, but I was surprised how good my home-built speakers sounded now that they have a clean signal "with enough amp" to drive them to good levels. You can compare speakers to air pumps, and I was running 45 Horsepower air pumps with 15 Horsepower motor s when I was using the little amp.

Now I've got like 60 Horsepower, which gives me plenty of reserve capacity, or "Headroom". Makes a huge difference.

All the rotary switches and controls turn smoothly, and quietly, with no scritchy-scratchy sound, and all the lever controls do the same. The FM dial calibration is a bit off to my eye, but it's off a consistent amount from the bottom to the top of the band, so that's usually caused by the dial cord having slipped a bit. Easy-Peasy fix, and I'll do that when I take the cover off to replace a burned out dial lamp, and blow any dirt and dust out of the chassis.

This is the first "High End" FM Stereo Receiver I've ever owned although I've heard plenty. When some of my friends were buying things like this, I was buying things like Carillo connecting rods. Different priorities for different folks.

Ray Manzarek Explains "Riders On The Storm"

 The Doors were one of the bands I "Came of Age" with, along with Chicago, BS&T, Iron Butterfly, Cream, Traffic, Pink Floyd, Led Zepplin, and many others.

"Riders On The Storm" came out in 1971 as a track on the "L.A. Woman" album, and was a sleeper hit. It's in my top 3 Doors songs, and I've always enjoyed hearing it. Has a very haunting sound to it, along with Morrisons' dark lyrics.

Ray Manzarek explains where it came from, and how it was put together, and I think you'll find this an enjoyable ten minutes. Sorry I can't do anything about the aspect ratio of the video. Looks like it was shot in 16:9, but is playing back at 4:3. Oh, well....

And I can't wait to hear some classic rock on this new acquisition.....

 It's a "Silver Pioneer", Model SX-780, the baby of the line. If the speakers I built a while back aren't suitable, there's a local books/records.vintage audio gear store here called "The Bizarre Bazaar" that has some good looking classic speakers for some very reasonable prices.

It's Friday, the Start of a "Grounding and Bonding" Weekend!

 Sorry, but not FFF like Irish hands out.

Going to try and plant the first of my three ground rods tomorrow, and I'll be using my "Deep Root Watering" yard tool so I can at least get the first 30" of rod slid in before I use my ground rod driving attachment in a demolition hammer to drive it in the rest of the way.

Watering device:

This isn't the exact one I have, but it's very similar. It's a steel tube with a hard point on the end, and three holes to let the water out. You turn the water on a bit, and then push it down into the dirt, which usually dissolves and moves out the way, allowing you to insert the rod down to about 30". Unless you hit a rock, in which case you lift it up, move it a few inches, and start over. I'll leave the water on a trickle for a few hours like when I water the trees, and hopefully enough will collect in the soil so the remaining 6' of ground rod can be driven in.

And this yard has LOTS of rocks in places! It usually takes me three or four tries over by the ash tree before I can get the rod inserted beyond 6".

Once you have the hole made, you insert the ground rod, tap it down until it hits the bottom of your new hole, and drive it in the rest of the way using an adaptor:

In a demolition hammer:

I've done this before, and using the power tools is far better than battering the end of the ground rod with a sledge! It's also reeeal hard to smack a ground rod that's still 6' out of the ground and waving around in the breeze while you're trying to stand on a ladder. With another set of (gloved) hands to help keep the rod vertical, you just hold and guide the demo hammer, and let it do the work.

At the top of the ground rod will be a set of solid copper plates that clamp the rod, and allow me to mount the surge suppressors, as seen below, fully assembled.

This will be mounted at the house, just below my "Coaxial Entrance Box", where the cables enter the house.

At the base of each of the two 4x4's I'm planting as antenna supports will be another ground rod/surge suppressor, and those two rods will be bonded together with some #2 solid-copper wire. I'd go the full "Perimeter Ground" route, but the cost of the copper would be excessive, and there might be a code issue with bonding it to the main house ground, aka "Utility ground", which is usually how it's done.

More pix to come as work progresses.

Great Post From Stilton!

 If you haven't seen it, I recommend you go read it.

It's over at Stilton's Place.

OK, Back To Basics

 I kinda liked the SciFi theme, but nobody else did.

So to keep my half-dozen readers happy, I went back to a simple theme....

Not Sure If I Like This New Background...

 Yeah, it looks more SciFi than the equations on the blackboard one, but I don't like the interface to post new entries. AND, I lost my "Blogs I follow" list, and my "Link-O-Rama".

If I can get those back, I *might* keep this. Otherwise, I'll just go back to the "Classic" interface.

New Revolution in Cuba?

 Just heard on my ham radio chat group[s that the Internet is down in all of Cuba, and people are in the streets by the thousands.

Not sure where or when this was taken, but it was posted in the Ham radio group on FB.

From Twitter comes video of the "Black Berets" getting involved.

I'm tuning around the shortwave bands trying to get some info...

13 Colonies Amateur Radio Event -Recap-

 Well, I finally got the operating desk rearranged, got the new matching unit wired in and configured, and went in search of the 13 Colonies stations. This event in held yearly, the first week of July, and this year I thought I'd give it a try. Please excuse the crude wood blocks propping up the front of the radio. They were expedient, and will be replaced with something that looks nicer. And I have "RipTies" stuff I'm going to use to tidy up the cables dangling behind the desk.

There are 13 stations, plus three "bonus" stations, and whether you work one of them, all of them, or all with the bonus stations, you can get a nice certificate.

Some people sniff at it for being a "Participation Trophy", but events like this are very good for contacting states with few Hams, like Vermont. One of the QSL cards I have from Vermont says "Vermont-----AT LAST!"  across the top of the card. There are "Official" awards issued but the ARRL for things like "Worked All States", "Worked All Continents", "Worked All Zones", and at the top of the awards heap is the "DX Century Club" (DXCC), for people who have confirmed contacts with at least 100 countries. And within these individual awards are endorsements for things like making all of the contacts on each of the five "Classic" Amateur Radio bands, namely 80 Meters, 40 Meters, 20 Meters, 15 Meters, and 10 Meters, a total of at least 500 contacts. A friend of mine has the "Worked All States" award with a special endorsement for doing it on 6 Meters, the 50MHz band. It took him over 10 years to do it, but he did. Some people have spent decades "Chasing Paper", but I've never really done it. I had 42 states confirmed as a Novice in 1964, and most likely have worked all 50 states, but not all from the same location.

Anywhoo......A special event or other contest is a good way of seeing how good your station is, as the bands are crowded, and the signals range from "ESP Level" to "Blow Your Headphones Off", and it can be very hard to make contacts. A very strong ("S9" or better) station 1kHz away from a station only 5 or 6dB above your ambient noise level can be extremely difficult to receive. My little K2, while a very good, single-conversion design, gets all flummoxed under these conditions, and can actually be unpleasant to operate at times.

So how did the new Yaesu perform? Spectacularly. I've had a lot of radios over the years, both high-end, and bare-basics, and this rig is the best I've ever owned. The filtering is superb, and with the DSP, you can easily reduce the bandwidth to 1500 Hz, and still understand the other station. I can easily hear a weak station 1~2kHz away from a strong station, with no "Bleed Over" or funny Donald Duck sounds.

And I was able to contact 11 of the 13 stations, and one bonus station. I missed both North and South Carolina because I could never hear them, even using the "spots" on the DX Clusters to locate what frequency they were using.

Happy Independence Day!

 No, I haven't done that, but I applaud the men who did for their courage and bravery.

Anyway.....

  We don't celebrate the date, we celebrate the event which occurred on the date.

I know I don't have to tell this to the people who stop by here, as we also say "Merry Christmas", and not "Happy Holidays". I think we lost something when people started  celebrating the date, and not the reason. To most, it's just another day off work or school, and a reason to stuff yourself with food and drink, and that's sad. 

And I think it's a major part of what happened to get us into the condition we are now.

Enjoy the date, but please, remember the reason.

When Motor Oil Went From Cans To Bottles

 Another "I Remember...." story, sent to me by some friends.....

**************************************************************************************

Once upon a time, oil came in metal cans you had to pierce with a spout, so it was a surprise when I went to work at the filling station one day and they had motor oil in new plastic containers with a twist off cap. I wondered why no one had thought of it sooner. It was not long until I had a customer that asked me to check the oil. In the "good old days" we pumped gas, washed windshields and checked tire pressure upon request. The customer's car was low on oil and they requested a top up, so I got one of the new bottles of oil, twisted off the cap and put the neck of the container directly into the opening of the valve cover.

When I opened the bottle, I noticed it had a tamper proof cap, and the lower half twisted off while remaining on the bottle. When I pulled the bottle out of the valve cover, to my surprise, the lower half/plastic ring was gone! Where did it go? It had slipped off and fell into the valve cover. I sheepishly informed the customer that I could not see the plastic ring and would have to take off the valve cover to remove it. He was nice about it and gave me the go ahead so I pulled the car into the shop and proceeded to remove the cover. There were five of those rings in there! Apparently others had the same problem with the ring slipping off the bottle and either did not notice or did not say anything. The customer went away happy though.

Shortly after that, motor oil manufacturers seemed to revise their bottles so the ring stayed with the cap. I wondered why no one had thought of it sooner.

 

**************************************************************************************

I was a gas-pump jockey at a Sunoco Station a friend's Dad owned, but it was well before oil came in plastic bottles. He allowed me to pump gas, take payments, and clean the windshields. I could check the oil and air, but not add oil or fill tires, which required one of The Guys from the service bays to do. After a while, they convinced the owner I was smart enough to do these things properly, which he allowed, about two weeks before the summer ended, and I went back to school. My "primary" summer job was at a little electronics place, but my friend asked me if I could help, and I said sure.
