Question about Audio Players & Recorders
The resister called for is R202, which is a 1 Watt resistor and makes up a "snubber network" with C211, which must be replaced as it shorted, which caused R202 to burn out. This short will not show on any tester as the short only occurs above 25 KVAC from the spikes that this system typically produces. Do not replace C211 with same value capacitor, because it will also fail. The MFD rating must be the same to resonate with the frequency, but up the VAC rating. Engineers typically design these @ 12-25 KVAC and you need a rating of 35-50 KVAC, since the voltage spikes easily exceed 30 KVAC.

I haven't found the answere yet, but my RT2870 uses the same power supply board and this appears to be a known issue with this power supply board. keep checking this thread:
if an answer is found, it will wind up being in that thread...
also, if you found the answer, please post it to that thread, thanks!
