Hey Caution, just a question about your re-capping. Did you glue down the new caps, the ones that were previously glued onto the board?
In the process of doing my recap..

Can you give me the formula for the treatment you apply and if there is any trick in how to apply it? I can see most of the ingedients in the photo, but I can't see them all and I don't know about how much of each chemical. I live in Florida and we got plenty of sun. 

 

You need a bottle of "40 volume" hair bleaching cream. In the unlikely event you can't find the cream version you can add a thickener like guar gum, xanthan gum or arrowroot. Paint it over the entire piece and cover with clear plastic wrap to avoid drying out, and set in the sun for a while.  It's common to accelerate the process with a dash of Oxi Clean, but I'd skip that. 40 volume's hydrogen peroxide concentration of 12% is plenty strong enough as-is. You risk over-processing the plastic, which causes this pattern of white marks where the plastic originally flowed during casting, which is irreversible. A ton of info on blogs is out there from others' experiences, whitening everything from action figures to game consoles to sneakers.

Yeah I glued the five big ones on the amp board but it's not a big deal if you don't.

Amazing. It seems everyone on here is great at working on these old boxes. I find it very intimidating to start to work on these as I am just starting out and don’t have an electronics background. I guess you just have to get in there and do it eh? Anyone k ow of any basic electronic courses or any course specific to fixing old boomboxes?

Thanks for the  info, my friend. I think I'm officially scared to do it. It might be green, but it still looks pretty good.
