So I recently got a non-working SX-737 from a friend. When he had it it was working okay but, when warmed up, it would occasionally pop and the audio would and cut out for a bit. I guess he figured a recap was in order so he went ahead and did some work on AWH-033, AWR-057, and AWF-011. Somewhere in the mix of things it became a very nice looking paper weight. Now I have it and I'd like to resolve whatever's going on with it. I know from his notes that he replaced the following: AWH-033: 35v 47uf cap x 2 6.3v 220uf cap x 2 10v 22uf cap x 2 A726 S56G1 transistor x 4 (replaced with KSA992FBU) AWR-057: 50v 220uf cap 50v 100uf cap 50v 330uf cap x 3 16v 220uf cap x 2 35v 100uf cap 16v 100uf cap 25v 22uf cap AWF-011: 6.3v 330uf cap x 2 25v 100uf cap 16v 220uf cap C1313S54G transistor x 4 (replaced with KSC1845FTA) A725S56F transistor x 2 (replaced with KSA992FBU) I also know he referenced this post (http://www.audiokarma.org/forums/index.php?threads/deciding-what-caps-to-use.494440/) for finding the caps and transistors. So the current state of the receiver is this: it powers on but there is no relay click and no sound from anything. Not even the AM/FM or headphones. I am not super knowledgeable about diagnosing these things but I suspect that it's the transistors that have been installed incorrectly. I only say that because a) none of the caps were reversed or installed incorrectly and b) I know from talking with my friend that he was a little unsure on the orientation of the transistors. (I should also note that all fuses are okay.) That all being said I would really appreciate some guidance in figuring out how to narrow down where the issue lies. I have a multimeter (that's a little hard to read but it's better than nothing) and the ability remove/replace whatever component is needed. Any advice would very much appreciated!
