Antique electronic supply are my new favorite vendor. I was unaware of them until sushi box showed up.
Single ended amps have one power tube, and push-pull amps have pairs.Sounds pretty good. I was looking at the schematic and it only has the one el84 power tube. That's crazy. I thought you had to have a pair. I need to learn more about amps

I don’t know what you are talking about, but it sounds kinda hot…Single ended amps have one power tube, and push-pull amps have pairs.

One little friendly nitpick - you might want to make a little more room for those 5W resistors, and don't solder them flat to the PCB. They can get really hot and burn the board over time. It's often recommended to mount them a centimetre or so above the PCB to allow air flow around them.
I saw this on Mr Psionic Audio's videos on YT. It's amazing how much those resistors can discolour the PCB.
Apart from that - great work!
I don't know what thermal paste is but it can't hurt to over-do these things. Amps can get really hot and not just because of the filaments. I hope you didn't take what I said as criticism - it was definitely meant as a friendly heads-up! I'd love to hear the amp.
Fantastic work sir! Great tip on the dim bulb! A snuffer stick (aka thing-doer) is useful as well.
Did you mention what speaker your driving?
