A quickish response as it's getting a bit late here.
No problem with capacitors thanks Ed....
I purchased the entire stock of the long defunct Greenwelds including loads of NOS NATO packaged condensers. Maybe tens of thousands in all.

I do like the idea of a fancy cabinet.
The receiver chassis is pretty substantial being larger than an AR88 and the matching amplifier although slightly smaller weighs over 40 pounds.

My stock of valves includes a large box full of NOS KT66s so I plan to fit a couple of these and run triode connected?

Coil Q. It's the coupling winding using resistance wire so the tuning bit should be OK. I think it uses Litz wire.

Cabinet design proposals invited on A2 or A1 paper.
