There has been a lot of talk here about microphonety of the 6V6 tube. Has anyone tried tube dampers either silicone o-rings or the Herbie type dampers?
Could you space the top plate 5mm or so above the wood frame? You'd get good airflow all around the perimeter.

I'd get rid of that masking tape holding the power resistors together. The glue on masking tape dries out in weeks and the resistors will fall apart.
Just use longer screws.

Thanks Kodabmx....
It is an old pic only for testing. Now there is only one resistor with proper value to get 360V before the Salas Reg..

@Nikososkey. Could you provide a little more info on how you built your heater regulators and HV regulators? I love how you used the brackets to make use of the allowable space.
My heaters regulators based on Salas L-Adapter
L-Adapter
GB for Salas L-Adapter Board
And the HV regulator it is the Salas reg
Simplistic Mosfet HV Shunt Regs
GB for Salas SSHV2 regulator

Some Typical LEDs HP 1980
Some tests I ran a while ago. As the wavelength becomes shorter, red to green, the forward volts increase. Yellow & orange in between, Blue higher volts.🙂

Nice video*. So your build has L-Adapters for heaters on home made boards, also planning SSHV2 for B+. A BJT bias addition in the circuit. Why, you wanted to can scan for sweet spots?
