Pretty standard build, Edcor XPWR035, XPSE25-8-5K, Hammond 193J, 70uF motor run cap, .22uf Auricaps, EH-EL34, JJ-GZ34, Jan-Philips 12AT7WC.
That's really a great looking project. I very much like how you did the back panel as well as the switches for what I awesome are UL/Triode and feedback.

Yes, and one for switching the cathode resistor for EL34, 6L6, and KT88.

Default TubelabSE for 45 and 2A3

So,

I just completed a TubelabSE to be used with 45 and 2A3.

It's more "conservative" compare to the "Cinderella Castle" for the 300B, and everything went incredibly smoothly in the construction.

Particularities are that the two 10 ohm resistor to measure the bias are mounted off board under the measuring point, and I made holes, do that the bias can be adjusted without opening the chassis.

I found the chassis in Akihabara, the Tokyo electronic district. The iron comes from Thailand, from Silk. The owner was very kind and he custom made the power transformer for me.

I am still thinking about a version of the Tubelab SE with regulated PSU, but it will take a while.

Davide

P.S.: This time pictures were taken with a Nikon
