Default Anyone has a schematic from Raleigh Audio Extreme Preamplifier

Hello,

I desperately need a schematic for this preamp I own. The top version (whatever it was called, Dual Differential something...). It's collecting dust for far too long, since the repair of failed CCS in PS ended in a degraded sound quality that never reached original so I just stored it under sofa.

I need to bring it back to optimal condition and see if it will be of use in my system, or I should cannibalize it for LL iron.

I wrote to Raleigh but something's wrong with their mail, i don't know if they changed it.

In case you can help, contact me via PM and I will provide you with my email.

Much appreciated!

Try Kevin Carter at K&K Audio. I believe they are affiliated.

It's doubtful they will give you a schematic, but probably they will sell you the part that you need.

If you don't know which parts you need, that's a problem.
Why do you think the current source circuit is at fault then?
Contact them and see what they say.

David Davenport from Raleigh Audio responded promptly and I've just supplied him with the pics of the boards so I get the corresponding papers.

It is good to know there's still good and responsible people out there....
