I've been lurking in the background for months reading, researching, and learning a ton and decided to take the plunge and recap my SX 1980. I've followed to a tee advise and direction from the likes of EchoWars, MarktheFixer, matted, and many others and it finally came time to put it to the test. The mods I did were all on the PSB with EchoWars Current Sources (his design), and new relays (LY1-0-DC24 & MY2-02-DC48) with the jumper wire running from the + of the 3300 cap to pin 2. The Sources were tested good. All caps on all boards were replaced and the receiver put back together except the amps are not hooked up. I left those unattached in case something happened. I finally bit the bullet and did the DBT with 100W, 150W, and 200W bulbs and sadly to say all were bright. :thumbsdn: Things I noticed are neither relay kicked on. Nothing, however I did notice the Current Sources light up briefly for about a second before turning off. I turned off the DBT and turned it back on and the Current Sources lit back up for the second then off. Nothing else was noticed, no pop, no smoke, no lights, no relays kicking on. I checked for loose wires everywhere and found none. I suspect the S1 relay even though it's been replaced but who knows. I'll will be honest and say my electrical experience is limited. I can read schematics, do all the mindless mechanical stuff but when it comes time to actual troubleshooting I'm lost. I know this is not the best way to introduce myself and I apologize but for those of you that know this unit well I would certainly appreciate the help. Thank you to those who are so generous with your expertise! John
