Things are getting hot. I measured that with a power meter. The power
transformer can really cook - it has far too much winding resistance.
It is actually a souped-up dinky lab demo model. I wound a primary
for it that brings the core close to saturation (Imag around 6A) to
get more volts out. Mains in is 230VAC. The cap is also a bit lossy
and does get warm. But mainly the transformer.
