[Boatanchors] Paralleling HV Transformers

[Byron Tatum]

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
