Sumo Artemis pre-amp

Ian Sampson · 7th January 2009, 09:32 PM

Please could someone help with the circuit diagram/schematic?

I need to know what parts Q112 to Q117 are and what connects to what.

My Artemis is being repaired after a catastrophic power surge and a lot of components were burnt out. These have now been replaced by the Audio Laboratory and they report that audio signals are whizzing around the boards but they stop short of the output stage and this is the only part missing from the circuit diagram.

The lab says that the above tracks/parts are covered in a residue from the accident and they can't tell if the circuit board is burnt or damaged. Obviously they'd like to know before chipping away merrily.

Many thanks in advance

Ian

Is there anyone who can point me in the right direction?

I even tried emailing Cullen Circuits but Rick Cullen replied that he doesn't have this specific schematic. He also said that he's forwarded my email to James Bongiorno, but i've already emailed him directly from yahoo groups and had no reply.

Desperately desperate

Best wishes

Ian

Ian, did you ever get sorted?
I know it's been years, but if you are still out of order, I have a working Artemis. I can take close up photos of everything for you and take mesurements if you wish.
