At my wits end here. So a while back my 8500 just stopped working. No fizzle, no sound drop off...just relay off. So I recapped the switch and power amp assy. I put in ALL new transistors while I had it all apart. I have done at least 20 amps before this so I know I got them all in right. I checked and re-checked. Put it back together and worked awesome for about six hours all the while monitoring the outputs heat. My idle and offset were dialed in perfectly IAW the manual. No DC from the speaker terms. I checked ALL the voltages at all pins and trannies and within spec. Still no relay. Changed the trannies and caps in relay circuit, nothing. I am out of troubleshooting steps that appear in these forums, so any guidance would be greatly appreciated. I will post my voltages soon as I neaten up my desperate hen scratching. Thanks.
