I think I have one of those adapters somewhere. Seem to remember buying one years ago. But a USB model without adapter would be current/up-to-date.

Thx-RM

Well I have been putting of doing a volume control mod,Should have did this long ago ,so much ezier to set up the balance on the 8 different channels on 2 dcx's,I did basicly whats been posted I used a 10K pot and I jumped the mute and used the pins on the op amps pins1 and 6,I put a 1K resistor inline and a .001 cap across a 47 uf cap,I used some better 47uf caps ,I think the ones I removed were as old as the unit and cheep,LOL. I think some oc-cons for the digital section and maybe some new power supply caps,
Has anyone that replaced the power supply with a linear one care to comment?
Clocks seem to be a big inprovement also,
Thanks,
NS

That's a hard one to ask the designer
It's not dramatic, but for me it did change for the better.
Just personal opinion.

BTW Pilgham Audio, the guys I send those link for, told me there was a fire in the server room of their provider and they are now trying to rebuild there site. I think the pictures aren't rebuild yet as of Friday morning.
If you want info probably best to mail them.

Yeah the challenge was to manage space and heat dissipation for a linear regulator in that tight space.
At the end I selected an external wall-wart transformer (12VAC) that directly feeds the 5V, 3.3V and 6.2V regulators. A small, PCB-mounted custom 12VAC to 2 x 18VAC transformer drives the +/-15V regulators.
I even succeeded to re-use existing mounting holes in the box, so no drilling required!
