[Boatanchors] 6SG7 Question

[Sandy W5TVW]

Might be to supply the Russians?  The bulk of the AR-88's went to England, but
I hear some went to Russia and also Canada.
I have an AR-88 here.  Has anbody come up with a good product detector
mod. 
that doesn't butcher up the receiver?  Should be a dynamite set with a good
product detector!

I still don't think I have the IF system aligned properly.

73,
