    I totally agree about going ahead and changing out the resistors in the 2507 boards before anymore testing. There are a LOT of...

    I'm back now. Everything went just SUPER!! I set the DC Offset to +-1 MV without any trouble at all. Then after about 15 minutes I...

    Absolutely. I will take about 4 shots of it 1/4 of the board at a time so the magnification is good enough for you to see everything....

    After we get the 4-2507 boards that I am fairly confident in tested and set to your satisfaction I want to get all of the resistors...

    I don't remember for sure but I think I have replaced them on ALL of my 2507 boards.

    So, after I hopefully get the bias and dc offset set on the amp with this 2507 board are we ready to try the NEXT 2507 board?

    No, I haven't fired up one of my receivers OR transmitters in over a year due to my health.

    All of the VD1212 diodes have been replaced by 1N4198 series diodes. I'm not saying that the amp is going to do what it did in the...

    I haven't counted them yet but I think you are right. I will have you explain more tomorrow about the bias rising so high with program....

    Now that really makes sense. When I had nothing playing thru the amp I had no bias. It was when I started the cassette that the bias...
