Here is a real simple test.
1. Hook the two transformers in parallel and properly phase them so as to cause
out put sparks across a safety gap.
2. Disconnect the gap and with one pair of outputs tied together, hook a 1/4
watt, 1000 ohm resistor between the output terminals on the other side.
4. Crank up to full power for about a minute.
5. If the resistor smokes or gets uncomfortably warm to the touch*, the
transformers are too different to be used in parallel. (deltaV > ~8.3 volts.)
* Only touch after turning off power.
Hope this helps,
