They have changed a bit since then, and then a new one got made.
the amps: cascaded diff amp/LTP stages( 6SN7>>6BX7 ) to PP KT90's riding a Dynaco A441. Configured in pentode mode with cathode feedback using the tertiary winding.

B+ is ~380, and the finals are idling at 110 mA for Class A operation. Choke input PS with GE motor-run caps.

I put a bit on the new ones at the link. I have gone DH for the time being.

Douglas

here is a pic of the linestage. Shunt regulated with VR tubes, and active loads on the plates of the 2C50 ( it is now an adapter rig holding 2 12B4A's ).

I took that pic before I salvaged a volume knob from a scrapped Tek 517 scope I was using for parts.

Not sure what you mean. Drying time?

Kick plate is indeed the chassis plate.
I just priced copper and brass 20 ga. 6x10 plates at
onlinemetals.com, they were $16 and $12 respectively with $10 freight charge

2 things to watch with the mitre and tape:
1) No matter how I have cut the mitres, there are always some gaps; easy to fix by saving some sawdust and mixing it with a little white glue to make a paste and filling
2) I have switched from white or yellow carpenters glue to the dreaded polyurethane because butt mitres with the former just aren't strong enough to hold up when you plane and sand or, worse, try to chop or rout holes for plugs and such

Definitely chop all mortises before glue up.

Highly recommend cutting dadoes for splines to strengthen the joint
