Hey all!

We finally acquired one, after searching for nearly 25 years...it's an excellent condition SL4040G+ from August 1998 that was filled with 32 channels and the last bucket empty. There's a few gremlins to sort out, but it's all wired up with a new SMPS that our tech designed and built and running beautifully - the sound is unreal, and we couldn't be happier.

So, onto a few questions. The last bucket came empty from the factory with blank panels over it, and I've acquired a few channels to install into it. However, it won't power up as the others do - I would assume I'd see VU lights, but I don't get that or power to the channels I've purchased. Is there something I need to enable or activate somewhere to get that last bucket to work? I know the 20v rail switches and breakers are there under the patchbay, but are there fuses anywhere inside the desk to make that last bucket work?

The channels that I found for it are three 6kG with black EQ three 6kE with brown EQ and two 6kE with black EQ.

Any help much appreciated!
Thanks,
Sig

I popped off the bottom panel after tracing what I think is the main power run to each bucket, and this little relay board of some kinda was just sorta hanging there...I don't really understand how it's supposed to attach, and it looks like the bracket was broken but nothing seemed to fall out.

I also tried adjusting that potentiometer on the bottom, but no difference. Is this little guy faulty?

I actually just removed it and plugged in the power direct as I noticed the 4th bucket didn't have one of these...and we now have power!

What is this board?! And do I need it?!?
