Hello
I have a issue with psu DVE DSP-508A. I cant find right resistors described as R5 and R6.
Part list is incomplete.R5 50??? R6 1/4watt? On board was 2watts 3.3kohm.
I removed old ones (looks burnt) one is 47kohm next 330ohm (on ohmmeter)
At this moment im totally confused. Please advise.

Re: PSU repair issue DVE DSP-508A for Atari STFM
Both measured values are correct and also match with the color code. The list/BOM is incorrect I think ...
Do you really have to replace the two resistors?

Thank You
Not yet i will order them soon. I just need to be sure.
So that should be 2watts, 47kohm and 330ohm.

Re: PSU repair issue DVE DSP-508A for Atari STFM
Ok. R4 on manual is described as 3300ohm
This one i measured one is 333ohm, coulor code looks like 330ohm (photo)
R20 47kOhm, ok
On photo you can see how this is described on the board.
Board is rev.0
Probably i have different material specification. But is described as for DSP-508A
