Dude, that is great.

 

So happy to see some progress on this, the RX-5050 was the only pot option anyone could find up until now. Good luck!

Turns out it was wired in right, swapping the original volume pot back in made no difference.

Won't know until I fix it, but maybe L/R short has something to do with treble?

Just like that, outta nowhere!

When I first opened it I saw the second wiper still in place and thought phew, only one broke, but it was just sitting there.

Right after I fixed this, the bass control wipers fell off! Some JB plastic weld and both are back. This is probably the best way to fix these since it keeps a very low profile like the original rivets, to prevent unnecessary rubbing/friction against the tracks once reassembled.

Almost. The volume pot has two extra pins for loudness taps, but you only see seven because one side of each pot uses the same pin, since they both go to ground anyway. Here's a diagram of the volume pot https://boomboxery.c...matic/?p=339312

Panasonic rx 5050  pot will not work right  that boombox does not  have a loudness spot  and a few other dead spots  its all on this web site about it   



Ok there was a post of a member looking for a pot of a jvc m90 that was broke.. I sent him this pic so he would know that the Panasonic rx 5050 also uses this pot for those that some day have a broken one hopefully never but its good to know :yes: :yes: :yes:
