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.


Absolutely! Hope that more owners of this sub will benefit from the fix. 


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


Thank you for your help. I will start looking for them.
