Title: PPIMV on Davoli-Krundaal UP160 - Is possible to find 33K Dual Ganged Pot ?
Post by: kagliostro on May 23, 2021, 06:05:15 pm

The Davoli-Krundaal UP160 Power Unit uses 33K grid leak resistors

assuming wanting to insert a PPIMV that uses 33K pot (replacing the resistors with potentiometers)

Do you know if is possible to find a 33K Dual Ganged pot ?

I searched but didn't find it

Thanks

Franco

Probably the wrong century. Just use a 50K and don't tell anyone.   :icon_biggrin:
