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.?

And linear with solder lugs with switch (for TS-lift/raw switch).

Thanks. I live in Norway
Would a 50k linear work better than a 25KA or 250ka?
