    Unjamming an immaculate Technics SL-5 (with photos)

    Hi all, first post! I find myself surprisingly expeled from Vinyl Engine [1] and instead of faking my way back in I've decided to turn a new leaf and start somewhere else. I bought a Technics SL-5 a few months ago which was advertised as being in perfect working order. This was close to true...

I wanted to try and recap the thing as a sort of last resort but the service manual doesn't really help too much. I could probably try and guess but the capacitors for...

    Sansui Au-666 Error on Schematic PNP Driver/Output Transistors. "Correctly Drawn/Fixed"

    So I noticed an error on the AU-666 while tracing all my wires back throughout the entire amp. Based on evidence left behind, this was probably a revision Sansui never fully finished in the manual. They show the collector of the "TR813" 2SA537 driver transistor going to Pin 8 on the Driver PCB...

    Pioneer lx 440 reciever sounds distorted via speakers but fine via headphones?

    See title. I was looking around online and read a thread where someone fixed the issue by recapping the power supply. I am pretty sure this is necessary regardless considering the lights sometimes dim a bit out of nowhere. But is there anyway to make sure that this is indeed the issue?
