Closer inspection under magnification shows a couple of spots I thought were adhesive are actually scratches. The rest is coming off slowly as I have time with Gun Scrubber and denatured alcohol.drjimhttps://www.blogger.com/profile/05647484115197408897noreply@blogger.comtag:blogger.com,1999:blog-4901205574058136834.post-83288512994117528622021-11-14T20:24:10.534-08:002021-11-14T20:24:10.534-08:00You might consider trying some Gasket Remover spra...You might consider trying some Gasket Remover spray from an auto parts store, for tape residue.

Gives the test equipment required, all the levels to set things to, the test points, and a complete alignment procedure.<br /><br />Setting the bias current is easy-peasy. Turn it on, no inputs, and set two pots for a specified value.<br /><br />Since it's on the bench, and I have the manual and proper test equipment, I'll go through everything.drjimhttps://www.blogger.com/profile/05647484115197408897noreply@blogger.comtag:blogger.com,1999:blog-4901205574058136834.post-81546388480828319102021-11-13T16:56:43.799-08:002021-11-13T16:56:43.799-08:00drjim, do you have the factory specs for the aligm...drjim, do you have the factory specs for the aligment and amp bias adjustment procedures?
