Reply to "2 transformers on same track"

It's not a good idea, period. The only way this works is with parallel 135 or 180 power house bricks fed to a TPC-300 or 400 device. The only reason this is because that's what the TPC was designed to do.

PW transformers are not identical inside. The windings could be slightly off. If the voltage isn't identical, you will get back currents in the lower voltage transformer and that's not a good thing. A modern switching power supply is worse. Most of these devices used modified sine waves that alter the wave form. Same issues if the devices aren't EXACTLY the same (actually worse since there is more than just a transformer winding to deal with).

If you need more power, buy a higher rated unit.
