Hi,

Big, fat, toroidal transformer. Very nice. Is it Class A or Class A/B? If it's pure Class A, it would run very hot and your electric bill would increase exponentially.

I once kept my take-out lunch warm on top of a giant Class A power amp we were doing listening tests on (with a buncha other amps) at the NRC in Ottawa many years ago.
