    Needle Replacement for Philco Phonograph

    I, for the life of me, can not figure out for sure what needle I need to purchase for my stereo. I got this console from my grandma and I can with 100% certainty say that the needle has not been changed since the 70s. I have the user manual for the console, but they do not list what needle is...

    Pioneer SX-580 Multiple Issues!!!

    Hi all, I recently picked up a Pioneer SX-580 and it came in rough condition but, still worked! Upon further digging, most of the capacitors where shot and the FM tuner potion would not pick up any stations, even with a antenna attached. The only time the FM worked is when it was in mono FM...

    Pioneer SX-780 Problems

    Hi all, I was able to pick up a Pioneer SX-780 for $50 today. It does have some issues. It powers on and all the lights come on. The relay doesn’t click on nor does the FM meter move. All the fuses seem to be intact. Any ideas on what and where to start troubleshooting? Thanks so much!

    So I just bought a vintage Pioneer P-D70 CD player on Letgo. When I came to pick it up the guy plugged it in and played a disc and it sounded great, I tried most of the buttons (FF, Rew, Track skip, etc) which worked fine. Then when I brought it home it worked fine for about 10-15 minutes, which...

    Technics SL-D202 Auto Return issue

    I purchased an SL-D202 a few years back that looked pristine but had a few issues: the platter would spin whenever it was powered on, and the auto return did not work. Also, speed would fluctuate, but that was due to the pitch control needing a good cleaning. So I opened it up, cleaned all...

    SX-1980 Quartz Lock Issues
