Power Transformer for Class A Amplifiers -- What are your experiences ?

[Melon Head]

Thanks Patrick. I should say that I haven't spent much time looking either.

I should also state that toroids saturate faster than EI or R core, and are therefore more likely to buzz.

Another way to avoid this is to wind onto a larger core.
Sumr and Harbuch will do this for you.
The other day I got a 500VA transformer wound onto an 800VA core. It is dead silent
