Chuck -
YEAH!! :-) The "diagonal" one is a cobble job that has been stuck
across the Both have been replaced. The one parallel to the chassis
wall is supposed to be the 1000 @ 15V, but the "other" one is paralleled
across C90C in the Twist-Lok" cap, probably because the can is dried out
and the ESR is way up. And the guy was too cheap to fix it properly.
Simple if you have the CD.!

You "really" need my CD for the B-Line! :-)
There is only one large electrolytic in the area you describe.
It's C192, 1000 uF @ 15V and is the filter for the divider chips
on the Calibrator board.

what are the two big electrolytic caps under the R4B chassis
near where the power line comes in ?
I'm looking on the schematic, but really only am seeing the
multi-section can on top of the chassis.
These two under the chassis look like they've been replaced at
some point (long ago, not modern), and I don't like the looks
of them.
