Copland Csa-14 Manual3/31/2021
The main reason I am here is to get thoughts from members on upgrading my beloved Copland amp.Anyway, i was wondering if its maybe a case of having a look and simply rectifying these faults with new componets, or a more indepth look at what i have and upgrading aspects at the same time, with new capacitors, regulators, etc.Would welcome any thoughts and suggestions on the matter, meanwhile here are a few pics of my innerards.Cart: AT OC9 III, Shure V15 III, Bellex HOMC, Garrott K2, VdH DDT-II special.
Digi: Squeezeboxes. Yamaha WXC50. Denafrips Ares II. Amps: Copland CSA-29, Denon PMA250 II, a couple of cheap T amps, WHAMMY headphone Amp. Speakers: 1995 Castle Howard S1, 1970 Wharfedales, Dick Smiths 80 specials. Have noticed that two of the big caps are bulging ever so slightly at the top, so i will be replacing them in due course. ![]() Take a look at the volume pot, maybe a new one or a stepped attenuator of similar range and value. ![]() The vales are new (old stock)siemens items, so they are fine, they just lost the markings when the pins were cleaned thats all. Any advicerecommendations when it comes to caps, and rectifiers going maybe mundorf, not keen on alps though, stepped attenuators i may look into, any concerns over precise volume contol. It also gave me the oppourtunity to strip it down fully, have a look at the build quality and give it a clean and dust up. By rabid1981 at 2011-09-26 some nice big mundorf 10000uf 63volts instead. By rabid1981 at 2011-09-26 bare chassis, bar the transformer, and leads. By rabid1981 at 2011-09-26 almost all done now, replacements were a little bigger than stock so where they were touching in just two cases, i glued a tiny peice of foam between them. By rabid1981 at 2011-09-26 all back together and warming up By rabid1981 at 2011-09-26 nice night shot, turned it on, thankfully no hum or burning lol By rabid1981 at 2011-09-26 additioanlly the speakers hookups were replaced with HGC pure silver wire. Ive got an Exposure Pre and Power waiting for similar attention. Self built music server with 3 seperate linear PSU, Intel i5, 16 GB RAM no hard drive (various Linux OS).

The whole problem with the world is that fools and fanatics are always so certain of themselves, and wiser people so full of doubts. Bertrand Russel John.
