Part 2 of the repair process. This video covers crossover repair and driver replacement. All replacement parts were found on ebay over a few weeks of looking. Sansui SP3500 Info: www.hifiengine...
I recapped my 3500's a couple of years ago. I used 1% tolerance caps from Parts Express and changed the spring clips to binding posts. The caps made a night and day difference with the way these old Sansui's sounded. They really opened up and had much more presence.
These were not my speakers. If I remember right I did end up testing the caps with a ESR meter and they tested ok surprisingly. Customer wasn't interested in paying to having them replaced. Just wanted them working.
No need to remove the terminal spring clips. Just remove the nuts from both tone knobs and also unsolder the input terminal connections from the circuit board.
You have to desolder the spring clips from the terminals on the board. Then undo the pot nuts and then the screws holding the board in. When I did mine I also put better terminals on the back. Those terminals aren’t real good.
I just got a pair of these and unfortunately have a blown woofer. Tested it with a multimeter, totally dead. Any idea where I might be able to find a replacement?
Man, that head camera is not a good idea at all. Your head movements do not relay a proper camera movements. People get dizzy and in the end we throw up 🤔

It's also why mids and tweeters blow due to the caps being out of whack.
Thank you!
Very helpful 👌
Looking at caps is just the first step in checking Caps. They are 40 yrs OLD. Replace them already.

Great vid! it is really helping me out. Thank you. How did you remove the spring clips to get at the back of the crossover board?

Can I get the specs for the squawkers? I need to oder at least one for my 3500's. Thanks in advance!

Ok why is sp5000a speaker so heavy what’s inside of it
Great videos but that head mount camera is terrible. Please invest in a tripod.
Bad bad bad.
get this camcorder off your head because you're shaking

Lol, I know. I quit using it shortly after.
