Hi Kevin.

What is the issue with it, is it the mixer or the amp?

I don’t have the exact schematic for that exact mixer, but I do have several from that vintage and as most of circuitry on the boards is fairly generic between modals you are more than welcome to have what I have.

If you are interested let me know and I’ll zip them up and send them over, just PM me your email address.


Best

Alan

Hi alan, it's the digital reverb not working, the rest of it is fine.

I found an open circuit reverb fader and a capacitor on the reverb board with the leg rotted off. None of which made the slightest bit of difference.



I'll PM my email

Hi Alan

When I owned Carlsbro we had a few of these into repair but i no longer have the drawings. Suggest you try and get hold of Mailk. Give John Roberts a call on +44 (0)7966 13 31 39 as I am sure he can find what you need or put you in contact with Malik.

Hope this helps
Andrew
