I had some AC ripple in my model 255 power supply so I set out to
replace the electrolytics.  I doing so I beleive I mixed up a connection
on a board in the power supply. On power up I got a bit of smoke - hate
when that happens ;(

So, I have no schematic and was wondering if someone can point me in the
right direction.  For starters the connections I mixed are a couple of
jacks, one has three pins and has yellow wires, the other is 2 pins and
has green wires.  I thought is was all one connector when I disconnected
it.  For a point of referrence, this board has the connection that goes
to the lamp and the amp meter on the front panel.

I'm thinking I blew the two transistors on the heatsink in back, the
2n5301's
and I'm not sure on the others.
