That NiCad pack is part of the power supply and as Jeremy points out is part of
the filter system.And so one needs to restore it as part of the instrument
as even the 28V external power supply floats these cells and trips power
interruption indicator if lost
Power supply is not terribly
How did you come up with the 33,000 uF number, Perry, and is it one big
capacitor or lots of little ones tied together? The big cap will also
filter out some of the remaining ripple in the power supply that may
have been managed by the ni-cad battery.

Hi,
The battery problem becomes more convoluted every day. Due to family medical
issues I have not been able to do any testing/repairing.
The 105B charger is set up for nicads using some selected un-alterable charging
rate so to use an internal lead acid setup requires a different ps.
