Since I'm waiting for some parts to get here to (hopefully!) fix the IM Analyzer, I decided to do a quick check on the THD Analyzer. All the capacitors in the THD (Total Harmonic Distortion) Analyzer have suitable working voltages, I have those values in stock, and they all passed the "Eyeball OK" check, I'll go with them for now.
First thing I noticed is that one of the rack handles for it is bent.
I checked the eBay listing photos again, and the handle is straight, so it must have happened in shipping. I unpacked this in the garage, and set it aside as I was busy with other stuff, so this one's on me. I thought they were cast Aluminum, but it weighs more than Aluminum would, so I guess it's a Zinc alloy, like "pot metal" or Zamak. I think if I heat it up with my big heat gun, and carefully apply pressure, I can bend it back.
The big surprise was when I pulled the covers off, and found the chassis is bent, too.
So I pulled the power transformer and the circuit boards, and see how well I can get this bent back.
And it's another filthy unit, having been stored God knows where and for how long.
When I saw the bent chassis, I almost consigned this to the scrapyard, but since they don't come along very often, I'll try and bring it back with minimal expense, maximum elbow grease, while keeping an eye out for a replacement, like an old HP 333A analyzer:
The Heathkit is a clone of the HP, but much better built. I'd gladly take the HP over the Heath, but they tend to be a bit more expensive. Maybe I should just bite the bullet, and start looking for one.....
