An optional Telefunken quenched gap is suggested. This used copper
disks separated by mica washers approx. 6 inches OD and 4-1/2 inches ID.
Can some one suggest a source of these washers? Is there a modern
substitute for mica?
Thanks,

Use micalex for the mica.

Those washers were only a few thousandths thick and I've never
seen Micalex anywhere near that thin. Have you? My Amrad quenched
gap of about 1917 uses 0.032" white fiber washers and I haven't been
able to find any replacements for a couple that are burned. I have
some black asbestos-based gasket material in the right thickness but
have never gotten around to see if it will handle HV. Anybody
know? By the way, making a quenched gap is not a simple task.
