Re: 3325B fail 026 - any advice?
Hi, Looks like A3U11 is suspect, the voltages on TP4 are not at all what the SM says they should be. It's an MC1495L multiplier, I'm just going to replace it and see what happens. Szabolcs Szabolcs

Re: 8642B displays A6A1 transient failure F3 when audio peaks at FM mod input

I have two 8642As, one working and the other has had A6 issues since I got it, FM modulation never worked. Recently it developed A12 unlock issues also. I am guessing some of the varactors may be bad,
