SX73 ballast info wanted
 

I just looked at mine, the lettering on the top is barely readable,
but it looks like the same as yours....it clearly says AMPERITE, and
the numbers below at first looked like 0-4, but upon closer
inspection, the 0 I'm pretty sure is a 6. Don't know if it's the
original, but if yours and mine have the same number, that's probably
what's supposed to go in there.

CORRECT HALLICRAFTERS SX-73 BALLAST TUBE?

I was hoping to hear from anyone who has a SX-73 Hallicrafters or the
military version R-274, R-274D.
What I'd like to clarify is what is the correct ballast tube type (number)
that is used in the octal base socket. Mine does not have the original
ballast tube in it. The type in mine is a type 6-4 AMPERITE
ballast/regulator tube, and the receiver does work. I just want to be
assured this is the closest match
for the "octal base" ballast tube originally used in these receivers, or is
this type indeed correct . What type does your SX-73 have in it?

Thanks, Dan

Hello
Just had a quick look and the Ballast in my sx73 is 7H-4B. Someone has
written "Amperite 6-4" in the manual as the parts list doesn't give any part
number.
Just out of interest where does one get the lamps E5&6?

Sorry, that should be the lamps that are designated R101 and R102.
