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

Glad to hear you got it fixed. It's great that there are forums where we can get together and pool our knowledge to keep our stuff running.
Don’t know if someone can help me out in where I could buy all these parts. I have a sub Gen 1. I will be doing it myself hopefully everything goes smoothly.
condensator smd 1210 1uF 100v (C85)
resistance smd 0603 1K ohm 01B (R37)
resistance smd 1206 1 ohm 1R00 (R77)
Transistor 2F SOT-23 0,8A 60V (Q16)
Transistor ZXMP10A13FQ 7P1 (Q10)
Diode zener B280 13-F (D15)
Hi Aghitman77, you may find these components in sites like Digikey, Mouser or Aliexpress from China. Perhaps Aliexpress is a good place to start for cost effectiveness. https://www.aliexpress.com/
Hi,
I bought all my parts from Aliexpress. Q10, Q16, the caps, resistors, I also replaced R37,R77. Ic TL5001.
Q16 is a 2N2907 I used a 2N2222
.D15 is a 2A 100V Shottkey, I used a 2A100V. Not a Zener
Check R37 and R77. Both were shorted or open
The parts are super cheap at Aliexpress. L paid more for the shipping than I did for the parts. The delivery date is 3 to 4 weeks.
Good luck
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
I have the same issue with my sonos sub, burnt R37 but i dont have the tools or skill to perform this repair. Does anyone know of anyone who offers a service to repair them?
