Phase Linear 400 pots

[John Prange]

Does anyone out there possibly know what spec audio taper and linear taper potentiometers an Energy AS-180 subwoofer takes? I dearly love this big old woofer and both pots are shot and need replacing. They are both labeled “100k”, but I’m uncertain as to wattage... Any thoughts out there? Thanks!

Usually a letter will indicate taper on a pot. Is 100k all that is written on the pot? We need all the information. Too much us never enough.

Might want to post question with correct title on speaker forum.

Welcome to ak.

My apologies, I should have provided more info...
The audio potentiometer is engraved with
“SH B100K”, and the linear potentiometer is engraved “SH A100K”. And I think these numbers are actually rolled-embossed - not actually engraved.
Obviously I’m a newbie, not only to electronics repair, but to this site! Thanks all for your patience!

First one has a B taper the second one has an A taper. Standard terms for pots, but they did change based on region of the world

will explain it. You might be able to measure them at spots to see what taper they are.
