On the ebi card
Replace the two 100uf caps with 220uf/50v caps.

Replace the 3.3uf cap with 10uf/50v bypass with a .1 wima cap.

I opted to socket the ic position, and ran .1uf ceramic caps in the positive/negative rails to ground.
Originally i used an opa1611 which worked great, but want to use a dip format opamp, so i ordered some lme49710 for the EBI card. (Looks like those have become hard to get).

Here for the gear

EMI Board

Hi! I've just picked up a 16ch 3000 and this thread is a godsend!

There doesn't happen to be a schematic for that EMI board by chance? I'd love to knock one up and A/B it with the transformer.

Also, mine has been sat in a garage for what seems like a very long time and I'm having some troublesome pots. Did anyone change the pots on theirs for a modern equivalent?

It's missing a couple of button and pot caps too and I'm struggling to find spares or at least a very close match. Does anyone have any suggestions?

Thanks again!

Are you having noise issues with yours? Is it noisy? I'm trying to find the source.
