Audio pots

[Erik Aa]

Hi. I am planning to build an AA864 Bassman, and according to the schematic there is a 50KA pot for treble on the bass channel. The only KA pot my supplier has is a 25KA and a 250KA (no 50…).

What do you recommend? 25 or 250? I will use the amp for bass.

Thanks!

I buy a lot of my stuff from CE Distribution as a "wholesale" buyer.  They have a consumer division and I found an 50K audio solid shaft pot here:  https://www.tubesandmore.com/products/potentiometer-alpha-audio-solid-shaft

Perhaps you are outside the U.S.?

Thanks. I live in Norway

Would a 50k linear work better than a 25KA or 250ka?
