Gentelmen:

I have an SB-230 Amp that I need a little help with. The other day the
33 Ohm resistor that is in the final tube socket of the 8873 blew apart
and took out the fuse and the diode across the Relay.  I found a new
relay for it and had to do some major surgery to get to it.  I had to
remove the left side which first off I had to remove the rectifier
circuit board.  Not a real big deal since I have a manual for it.  So I
thought..  When looking at the manual after a couple of the wires came
off there pins, it showd the..

Black wire goes to pin "A"
Blue to pin "Blue"
White to pin "C"
Red to pin "RED"
White with black trace pin "D"
Large blue wiht small clear sleeving to pin "B"

My problem is my rectifier board does not match this so I must have an
earlier SB-230.  My board is layed out in the following manner...

Blue wire from the transformer goes to pin "E"
Black wire with the white trace goes to pin "D"
White wire goes to pin "F"
Large Blue wire with the small clear shield goes to pin "H"
Red wire from the secondary of the transformer goes to ????????? The pin
broke off and looking at the solder side of the board does not help me
out either.  Does anyone have an older manual that can tell me what pin
that goes to on the rectifier board.
Can anyone shed some light on this so I know where the red wire from the
transformer secondary goes.

Thanks
