[ARC5] BC-453 Question BC-454 Also

[Dennis Monticelli]

Scott,

A quick way to assess your caps is to remove the chassis attachment screw
from each flower pot one at a time, slip a business card between the can
and the chassis, and then insert a current meter.  Slowly increase the B+
and see what you've got.  Leakage wise the odds are your caps cannot handle
the full voltage but might be OK running with reduced voltage. Others have
successfully operated their rigs that way.  FYI. I ended up replacing all
of mine in a BC-453.  It now draws 10mA on the 60V I choose to run it on.
Works great.
