Alpage AL-300 help

[Quadmatrix82]

hi Alpage AL-300 experts, I accidentally fitted a 10uf polar cap instead of bi polar cap today in this location - i couldn’t find a board number or part location on the board so im having a hard to time to trace where it is looking at the service manual.

I added a picture with the cap location

the deck worked for a minute and then a bit of smoke started to come up and i quickly turned it off SIGH….I have now replaced it with the proper cap but wondering what damage I could have done and where I should check to replace any other impacted components? This board is opposite the power supply board and hoping I haven’t done any terminal damage….thanks

Hi, seems to be C703, according to the SM it's 10µF/16V polarized (negative to GND).
You can check the two 22K resistors around but I'm sure they'll be still fine.

Ok I’ll check those resistors and change them to be safe I couldn’t tell exactly where the smoke came from lucky I had the lid off to see

O

Thanks for looking

Ok i had a look today, i changed the cap, resistors, no obvious signs of any burns - it plays and fast forwards but I’ve lost rewind….any ideas where to look?
