Someone got to this before me. I have no idea what may have been wrong or what has been done, except this. The CD player acts like it's typical failure symptoms, but it tests good and a different known good one doesn't work. All the flaky BC337's (it's in the serial number range), they were all replaced with 2N2222's. But transistor Q15 was also replaced with a 2N2222 which is a BC327 NPN not a PNP BC337
Could that one transistor cause the cd player to not work? I'll install a replacement, but the juke is over an hour away, so I'd like some idea if that one transistor could have been the problem or if I'll have to dig deeper.
Yeah, that is wrong...my chart for the transistor upgrade does not tell anyone to replace Q15! A mistake made by the person trying to upgrade.
