Pump Monkey Posted August 9, 2006 Share Posted August 9, 2006 So here's my opening volley as a newbie, your help would be appreciated. I currently have a RA3001 in for repair which has a completely burnt out resistor on the right hand power board, I have been phoning around my usual suspects to try and obtain a circuit diagram for this beastie, but with no joy, does anyone have such a document or can anyone point me in the right direction of someone who may? Usual rewards such as firstborn, etc to members who can oblige. I thank you. Link to comment Share on other sites More sharing options...
gingertom Posted August 10, 2006 Share Posted August 10, 2006 If you use your friend Google it comes back with over 2000 pages of info and hire co's regarding those amps. Haven't as yet (in the first 8 pages) found a circuit diagram of the PSU, but I am fairly sure one of the many hire co's service departments will be able to.

Rob_Beech Posted August 10, 2006 Share Posted August 10, 2006 had one at one point. I might still have it I'll look around for you. if not I'll try and contact the guy who gave me the diagram. I've got a 3001 in bits ....somewhere, I seriously dont know where it is though. theres an additional part to the board to the back of the amp slightly to one side. Its a little bit unreliable as its only connected via the wires and no other support. A common problem on these amps particularly if they are not screwed into the back of racks! Just some info for you there.keep an eye on the thread (not that you'd leave it) and I'll get back to you. Rob edit: lovely sounding amp by the way. fry eggs on the bloody things mind you.

dbuckley Posted August 10, 2006 Share Posted August 10, 2006 You could examine (or maybe even measure) the identically placed or numbered resistor on the other channel... Link to comment Share on other sites More sharing options...
Stewart Newlands Posted August 10, 2006 Share Posted August 10, 2006 Use the search function here! I live in the village of Haddenham in Cambridgeshire, we have a number of ex C audio people in the village and a little cluster of experts in the surounding area that have worked at c audio in the past, and have posted this information before and phone numbers.

Pump Monkey Posted August 10, 2006 Author Share Posted August 10, 2006 Thanks for the feedback so far, much appreciated. I'm on site this week but when I get back I'll get more info on the offending part and hopefully we'll get it back up and running. Thanks David, I may have been a bit misleading, the resistor is on a PSU board which is physically to the right of the transformer rather than part of the right hand channel and therefore it doesn't have a left hand counterpart. I have to agree with you Rob, they are nice sounding amps (when not being an oversized paperweight on my bench) had a few 2001's at my disposal for a while, but this is my first 3001, and thanks Wilf, handy link to Stewarts info!

lee.basham Posted June 19, 2007 Share Posted June 19, 2007 FYI I have circuits, product and service information for all C Audio products. I also offer a repair service. The resistor most likely to fail on that section of the pcb is the dropper resistor for the power LED so will not stop the unit from working. if you let me know the resistor number (off the PCB ) I can probably let you know what the fault is, alternatively call me on 07768 551482 and I can probably talk you through a repair.

Simon Lewis Posted June 19, 2007 Share Posted June 19, 2007 Lee, I suspect the OP might have sorted something out since last August, but your kind offer reminds me that there's a pile of RA2000s and 3000s in the store that need cleaning, repairing and selling on ;-) Simon Link to comment Share on other sites More sharing options...
