Gutshot of EHX Polyphase?

I'm trying to repair one of these for someone, and it appears the power supply went awry, charring all the components in that corner of the board beyond recognition.  I have the schematic and could probably do the detective work to "positively I.D. the remains", but time is an issue so I'd rather take the lazy route and simply replicate what's in a picture.

So, anyone know where I can find a clear colour pic of the component side of a non-reissue (5-knob, through-hole, black and blue) Polyphase?

Thanks, MIke, though I don't really frequent the other forum.

Any chance anyone here can tell me what goes where the 1 and the 2 are in this photo of the power-supply corner of the Polyphase board? I can't really see what part #2 is, from the charring.  What USED to be in position #2...well...let's just say the burnt part of the board gives you an idea what sort of damage to the part happened.  (Note that this is AFTER I cleaned things up)  I replaced the stock 220uf with 1000uf.

both resistors is all I can say.
If you pm me an email adress I can shoot you the pics I have, maybe you'll have better luck deciphering the colors (510M? I don't think so, Tim)

There IS a 510R resistor that is part of the power regulation.  PM on its way.
