[ARC5] 6AG7 and 6AG7Y

[Al Klase]

Bill,

Here's the listing from Lud Sibley's "Tube Lore II" a book you should 
not be without.  It fills in the chink between what we find in the usual 
tube manuals.



Micanol is mica filled Bakelite (brown stuff) for low loss at high 
frequencies.   All the one's I see were JAN spec, which generally means 
tighter inspection at the factory.   There might not be a lot of 
difference between 6AG7 and 6AG7Y in the real world.
