[Boatanchors] Paralleling HV Transformers

[Revcom Electronics]

Byron...

Not an unsual process in Broadasting.  To make sure
of equallizing any possible stray currents they use
a large series WW resistor of a few ohms in the secondary of each.
Dissapates start up surges and
acts as equalization.

Subject: [Boatanchors] Paralleling HV Transformers


Hello-
    If I could bother someone for an answer here :
        I have two identical HV transformers, each one does a great job at
around 1900 Volts at 400 mA. (in choke input with 10 mFD.) powering a single
tube (4CX400A) amplifier. I am getting ready to start using some dual tube
amps (4CX400A) and was considering paralleling two of the transformers, as
two of these guys are still more compact than other older style transformers
that would fill the bill.
    Are there any special precautions in paralleling the primaries /
secondaries ?
                                                        Thanks, WA5THJ
