Does anyone have a set of schematics for the C-Audio RA3001 that they could
let me have fairly urgently please ?

It's not a 'head', it's a 19" rack mounting pro power amp with line level
inputs. What do you want to know btw ? They are notoriously unreliable. First
job is to replace all the PSU caps that have been cooked by the hot exhaust air.
Then check how many mosfets are open.

I know an awful lot about it, having rejected it as an ODM product for
Studiomaster. I think it was that model.


The links to the service manual on the supposed C-Audio 'website', just seem
to take you round in ever decreasing circles via other third party vendors
of everthing you can imagine.

Harman UK bought them. And I could tell you a story about that too ! Ask there.
Except it's not Harman any more it seems but google that for starters. They've
moved to Letchworth. I think most of the C-Audio parts ended up shuffled into a
corner (I could tell another story) so they might be willing to get rid of some
unwanted and unloved bits. Unless they already put them in a skip (dumpster for
USAans)
