Default Re: Philips B6X12A on the fritz…

Ok 4Watt it is, the resistors that are connected to the power supply DC rectifier clearly look tired.

R66 (10K) is cracked, R1 (120R) seems alright, but I need to measure it to be sure.
Same goes for the 2K2 connected to R1, but it's blackened and hard to clean…
(picture 4, top left corner)

The others I need to measure, but the all seem (the ones I noted) tired…

Same goes for R63 and R64, but the Chinese owner suggested to change them for some tone improvement. You can see those two resistors on picture 5 top right corner (2 resistors) and R65 is burned on it's bottom by the aluminum capacitor that was underneath it…

So all in all the ones I've noted would be best to change. The rest of the caps and resistors seem alright.

Cheers,

Laurens
