Gotcha.
I have always wanted to build a Tube Power Amp with Regulated H.V. (B+).
When I can get around to making the PC board for the circuit, I will use MOSFET regulation and have a listen.
A Tube Regulated Supply results kinda too big and bulky.
There is an audible difference between tubes when they are operated with regulated H.V. (B+) as I have a 6SN7 Preamplifier
where I can flip a toggle switch and listen to both conditions on the fly.
The bitterness of poor quality remains long after the sweetness of low price is forgotten”
