Nice amp. What power transformer is this?

It's a local builder vlaartronic who has stopped winding unfortunately.

Standard EI96 Size: Guess that is a European size.

The transformer cover was standard. I drilled the holes and mesh. And the paint ofcourse. I got the idea for cooling holes because one had failed in South Africa where things can get pretty hot.

PS The output transformers are from a Sony R2R

Removed the magnetic iron around it. And devised a custom "enclosure"

The pcb is from a RH84 board I hacked to be able to use the 6n1p. (Different heater wiring than 12AT7)

All polyprop caps. DC link in the psu. And some "orange" drop types in the final decoupling on the pcb.
