Thanks for sharing your method! Do you also check to make sure the tubes aren't overheating, either at idle or full power?

Yep.

There have been many posts (eg Arcticbreaze )about the cost of trafos in NZ. The NZ/US exchange rate doubles the cost, and then P & P doubles it again.

I have to use what I have got when rolling my own, and very happy with the results too. The method mentioned gets me into the workshop instead of just reading and wishing.

I love clever hacks that actually work.

The opposite approach - the $100 vintage NOS papyrus-in-mermaid-oil capacitors and $250 crystal-aligned UFO-metal transformers - is what bothers me.
