Hi I have 2 problems with a rowe/ami R-86 record jukebox. They both have to do with the sound. I hav3 the 125 watt stereo amp 6-07438-04 and the preamp pcb 6-08552-02 the amp output pcbs i dont know model number the stickers fell off.
Heres what is happening and what ive tried so far to fix it. It has a static kinda crackle sound. I first changed speakers but that didnt work, then i de-oxited all switches and connectors also reflowed solder on all connectors and any other solder that looked bad(i found some bad solder but it didn't fix problem), then i changed all the electro capacitors on preamp and amp pcbs with nichicon kz muse capacitors exept 15uf 50v no kz model had to use a upj series nichicon cap and the large caps on otside of amp i didnt change. That didnt help. I also made sure speakers were wired correctly according to manual.this is where im at on this. I'm thinking now that the crossover caps might be bad or the large caps on outside of amp might be bad?
The other think that is wrong is the balace dial. When i move dial left side side stays on and right changes volume level. Im assuming that either the dial or the stereo/mono switch is bad.
Ive also reflowed solder on price pcb and button pcb
This is my first jukebox or audio repair. I have 20 some video games that i do all my own repairs on so know
