sonos gen 2 sub repair

I am trying to repair a generation 2 sub. I have narrowed the problem down to the secondary power supplies. R37 has been burned out, there were posts that said R37 is a 18 ohm resistor however the marking on posted pictures show a smt resistor marked 18d. This is not a 180 Ohm resistor.  Has anyone successfully repaired a sub 2 with the problem being the secondary logic voltages ? I believe I have identified Q16 and D6?  marked as Y2 and 2F.  Any help would be appreciated, as there is very little info on the web. Thanks,  Carl

What kind of a capacitor I need to buy for C81? For some reason I lost it I was cleaning the board. Thanks for the help.

I have no information on C81. It was not repaired or replaced on my fix.

I fixed the Sonos for a friend and I no longer have access to it.

You may try to contact others who are on the forum, they may be able to help.

Good luck
