Hi Keith...
Many thanks for the info re. the voltage/current available from this
transformer...
I hope you don't mind, but I'm "C.C.'ing" your response to the Reflector,
for benefit of others.
Thanks, as well, to those others who took the time to respond to my call for
help! Much appreciated...

Crrent available from these is not specified, but if you add up all the
rated filament draw of all the
