Looking to buy a manual (operations and/or service) for a Ballantine model 303 AC voltmeter.
What'cha got?

Thanks for looking up the schematic K7MCG. It's curious that Ryders shows a Ballantine 303 is a vacuum tube
test piece whereas the 303 I just bought is a solid state device. H-m-m-m. Not sure what was going on there....maybe the folks in Boonton NJ issued a tube type version called the 303 but then decided to keep the nomenclature. Anyway, I
thank you for taking the time to supply a schematic.

Pete, I appreciate your offer. As it turned out a buddy of mine has the manual and the price is right. ;)

Thanks to both of you for responding.
