Building first tube power amplifier, reccomendations?

My choice would be a 807/el34/kt88 power tube. SE

driven by a grounded cathode CCS loaded driver tube. 6n1p is a good, cheap one.

Tube rectifier plus choke.

This doesn't have to be that expensive. You only need 1 driver tube, only 2 power tubes. Cheap choke is only 10$. You can use tube rectifier because you don't need as much current. And you have lot's of room to expermiment and upgrade.

You can look here for volume pot, choke, socket, chassis, cheap transformers. Grab some silver wire for internal wireing while you're there.
0,5mm will be fine.

Audio Catalog

Use a simple CLC power supply for best performance. Use PSU desingner to simulate.

I would be curious to see what a semi-optimum schematic for that amp would look like, as I have some of those parts already
