[Lowfer] LW-MAX final amp components...

My LW-MAX has a BD-135 and a BD-137 in the final circuit. I found a broken
cap in the VCO a few minutes ago and repaired it, as there was enough lead
to solder to. Maybe this is why mine was so fluky. I also filled in all the
feedthru holes that weren't touched with an iron before. There were 90% of
the components that weren't flowed through to the topside. They are all
repaired now. There is a lowpass filter on the output that uses two 100uh
chokes in what looks like a T type filter. Since it is a double-sided board,
it would be possible to reverse engineer this card to produce a schematic.
That would take a while though. Some of the caps have no markings so a guy
would have to remove them and put them on the cap meter.

So far, BRO and RM are screaming in here down and up the band from the
loopers.
