have a few of these though just listed the one

they are pretty reliable

though not normally an issue as your taking the old one out

They are mechanically the same as the A4 and A8 just these are black

Soundcraft Series 400B 10k super soft feel fader Style:924M-10KA have a few of theseListing to be revised shortly I have a couple of these removed from scrap Soundcraft boards though they were I have had a new lot of these arrive and it seems there are some factory variations I have 2 with a black top like in the first photo they are marked 303M 10K I thought the 303m was just a lot number but maybe not. I have some new ones in they are wired differently marked 924M 10KA and have a silver top I think these numbers are just date lot
