    Pioneer SX 2500 (No AM/FM)

    Just ordered the parts, i appreciate the help. Ill post back my results once I am done! BTW, I had a 12 volt wall adapter lying around and I hardwired that to B3. FM radio came on! So at least I know once I fix the supply things should work! Next step after that is to change the lamps! I...

    Pioneer SX 2500 (No AM/FM)

    Hey Guys, Thanks for all the help, I will check B1's power output when I get home this evening.

That a way once I get the...

    Pioneer SX 2500 (No AM/FM)

    I will pull it apart tomorrow, I already have the manual I am just worried I will fry something. Is there a good tutorial you would recomend on tracing the power flow? I have a good multi meter. Also what is the best way to ID the incoming power to a given board? Sorry for the n00b questions :)

    Pioneer SX 2500 (No AM/FM)

    Hi all, I recently picked up a Pioneer SX 2500 to use as a phono preamp. I took it apart and cleaned everything and it is working well as a preamp. The speaker outputs also work when it is switched in to amp mode. However, I get no sound for AM or FM, no fuzz, nothing. I imagine that power is...
