Default Re: When to fit valve screening cans?

Can anyone offer reasons for fitting screening cans, or not?

Alan I will be most interested and will be following your progress. Are you following a set design or doing your own?
This idea is on my wish list. I will be looking at ideas for AM demod and if possible SSB demod as well. I have only stripped down some ex military VHF receivers and little else I am planing for a double superhet with odd ball IF's, but that is for the future.

Wish you well and keep safe.
