The Soviet transformer TS180 with a power of 180 watts has a primary winding with a thicker wire, 0.8 mm in diameter.

I have find it in my shed. It was made by me more twenty years ago.
That same TC-180 and a pair old good KT825. 
You can squeeze(got) two hundred watts out of it.

11:40 - all light bulb are on, but no loud vibration is heard. Almost nothing is audible, except spark gap.
AC vibration pumps have a trick - the performance of the pump can be controlled by a dimmer on a triac. Ordinary triac power regulator. Via opto-triac or solid state relay.

Hmm i doubt the transister is disipating 200 Watts if it was it would be a wast of power due to incorrect switching
like on and off time slope.
Or perhaps your using them as linear light dimmer then it might, but i dout it would live very long with max current
and voltage at the same time and dont forget at peek current flow you have that across your collecter Emitter 0.6
of a volt drop.

Sergh: Do you see a spot in the 2004 installation? orange coil or 2kW device ?
