I have an RW-12 (no d, same amp though) that decided to incinerate one of it's circuit boards when the secondary supply cap shorted out. Turns out, it was a fake Rubycon (YK series); it did not have the 'K' vent on top and it had 105° C printed on it even though the YK series is 85° C rated.

Well I bought it broken so I can't really complain, but this is the first time I've seen such a catastrophic failure resulting from a bad component (although capacitors typically fail open-circuit/low capacitance). I still intend to fix it, but this would be reason enough for me to avoid it if I couldn't work on it. My personal opinion is: don't buy unless you have a particular fetish for this model.

I suspect the cap actually short-circuited due to over-voltage (it was 100V rated), but I will not be sure of this until I repair the unit and measure the voltage. The last two Klipsch Sub-10's I worked on were running their secondary supply caps at 106V even though they were 100V rated (although the line voltage is 122V here).
