Soundcraft 400B mixer series modules tested input 4001 group 4002

I bought these from a local lad that was going to upgrade his series 400 mixer with some extra channels but in the end he sold his mixer or not had time for it.

They will come as a complete module you only need make two connections as far as i can see straight into the loom.

I will supply these with all knobs and fader but I only have a few fader caps but first come first served

I have for the 400 series

Module input number 4001 marked  SC1278 ISS 3

Module 4002 ( presumed to be the group output) SC1278 ISS 3

The pcb marking is hard to see under the metal at the fader end

I now have a mixer so all these modules are tested , I can re cap these if needed just tell me how many you need probably 10£ more per channel , less for bulk
