Simon Lewis Posted May 26, 2005 Share Posted May 26, 2005 Since the Crest UK website isn't up yet, contact Peavey who own Crest at: Crest Audio UK Great Folds RoadOakley Hay CorbyNorthants, NN18 9ET UNITED KINGDOM 01536-424750 (phone)01536-424003 (fax) If you have power supply problems, and are returning the amp, you should ask them to replace the inrush limiters at the same time. Otherwise, ask if your amp needs modifying and replace them anyway. Simon (proud owner of "CA18 Belchfire" amplifiers) Link to comment Share on other sites More sharing options...
STampie Posted May 27, 2005 Author Share Posted May 27, 2005 Simon thanks for the info. I have taken both rectifiers out and are awaiting replacements to arrive from the states, which I will refit myself. Andy from Peavey could not help at all. What are the Inrush Limiters and where would they be situated on the amp? why would they need to be replaced? Your help is greatly appreciated. BRYSON, Thanks for all your helpful info too, Easy to see why you are a Moderator on here with your wealth of knowledge. Link to comment Share on other sites More sharing options...
Simon Lewis Posted May 28, 2005 Share Posted May 28, 2005 Crest couldn't help? Was a reason given for this? I've sent amps back to them, and they've been quite helpful. Given my amps were under warranty, I dodn't open them up, but I believe they use a thermister as a mains inrush device. The CA18 used to have just one fitted, and it had a tendency to catch fire... In fact, reliability problems did quite a lot of commercial damage to Crest, and may be one of the reasons that they became ripe for takeover....

STampie Posted May 29, 2005 Author Share Posted May 29, 2005 Simon, Thanks for the info. My Ca9 has been bombproof til now but I got hold of it secondhand and it is no longer covered by warranty.I do have a good engineer where I work tho and we kinda figured once we found out what was wrong that we could just source the part and replace it!How wrong we were.... 8 week wait on the rectifiers!Coming from a company in Burgess Hill who have got them direct from EDI in the states.... Aparrently I should recieve them next week sometime. We'll see! Thanks again for you help STampie Link to comment Share on other sites More sharing options...
