Hi Vince! 
        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,
