[R-390] R390 NON A IF deck mods

[Dan Osborne]

OK - here is another "MOD" I have discovered on a couple of my NON-A 
IF decks -

V508 normally a 5749 (6BA6) has been replaced with a 6AU6 ???
Seems to reduce the IF deck gain BUT makes the S-meter zero pot MUCH 
easier to set !!

Anyone know if this is a "real" SB type mod or just a field tech hack ??
After resetting the IF deck pots I can't tell any difference in performance.

Comments ??
