    Pioneer sx 750 restoration

    I bought a sx750 recently. $100, damaged vinyl, cracked glass, damaged dial cord, bent tuning shaft, problems with balance (poor sound when set to 0, like channels mixing with one in counterphase), damaged caps, noisy phono stage, static when flipping switches. Started with gentle shower and...

    2SC1649 Transistor equivalent

    Good morning all, hope you are all well. I have been looking at an equivalent transistor for a 2SC1649 and am finding some conflicting types. I researched and found a 2SC2632 and have also been informed that a KSC1845 will do the job. After researching the KSC1845 I found the hfe and the (pc)...

    Sx750 screwed up

    Hi guys, I came here looking for help. I am attempting to recap my sx750 with very little experience. I redid the awk-065 boards and now my phono input does not work and has a loud static noise when I adjust the volume. So I noticed that I accidentally put a 1845 in The q4 location after I had...

    SX-750 loses sound

    Hi, folks! Before I plunk down repair money, hoped the experts would have some input on this. I've had an SX-750 that seemed to work pretty well, and sounded great. (Second owner after my mom.)

    SX-737 Not working after recap

    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...
