Tube pre Class D 250w power

[M Fowler]

Been pissing around with a champ cab tall enough for 12" speaker which will be a Milkman speaker, light weight.

250W 12" Neodymium Magnet Speaker
SPL 98.2dB 1W-1m
8ohm
7 lbs

Class D power amp and lower than I wanted power supply but will still get plenty of power.

Twin Reverb tone stack 12AX7 preamp tube.

Go get 'em, Mark. The fan is a PITA in bedroom setting--I add a switch and a power resistor to slow the fan speed.

What PSU will you use for the preamp tube?

I've done something similar, but the amp is outside the chassis to avoid to have a fan that dissipates heat with... heat.
