HP331 Distortion Analyzer Balance Pot

Hello,

I bought an HP 331A distortion analyzer.
The coarse and fine balance controls
are missing.

I have no schematic for it.

Does anyone know what the value of
these pots is?

I suspect they may be the same one
used on the HP333 (automatic), and
if so, the military federal stock number
is 5905-00-078-7402. Is there a
simple way to find the part value
from the FSCM?

Thanks.

John, the balance control for the 331A is a dual pot, 100 ohms/3000 ohms +/-
10%, 2 watts. HP part number 2100-1736. The OEM part was manufactured by
Centralab. Sorry, I don't have the HP - NSN conversion. Perhaps someone
else could help with that info.

Cheers!

John,

I plugged the NSN into my copy of the 2002 Federal Logistics Database
(bought it on floppies from a guy; can't remember who) and got the
following. I hope this helps.
