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 |

John 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.

John 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.
