Re: new builder

Hi Martin

As far as I know, they had no multiturn pots during WW2. Anyway, a singleturn was used. Must be linear!
I have doubts if a multiturn would be convenience. But you can try, no harm done.

Re: How I grind FT-171 crystals

Great! You gave a otherwise useless crystal a new life. How green is that?

Re: MkXXI Mk21: Looking for schematics

Hello Thomas,
Long time no read. Pity, you can't find a proper diagram.
Looked at your "products". Impressive collection you made. Beautiful examples of craftsmanship! I lift my hat!
cheers, Henk

Re: Dc-dc 45-390v psu?

No experience with them. Are they HF-stable? What is the own power consumption of the step up regulator?
Look at Banggood.com for the same unit.

Re: HOT LF-out tube

Check Grid#1 voltage. Should be minus 1 V.
