Amp KitsFrom mcjim--(at)--ol.com Wed Jan 11 16:09:16 CST 1995 From: mcjim--(at)--ol.com (McJimi) Newsgroups: rec.music.makers.guitar Subject: amp kit catalog Date: 11 Jan 1995 14:41:29 -0500 Sender: roo--(at)--ewsbf02.news.aol.com Reply-To: mcjim--(at)--ol.com (McJimi) Copeland Electronics ( PO Box 931, West Sacremento, CA 95691 ) makes a 50 watt, all tube, Marshall style amp kit for about $250. ( including transformers ) They also make a really cool "tube mod board" that lets you experiment with a 12AX7 in all kinds of circuits-gain stages, cathode followers ( these don't add gain, but they do lower impedance. Cathode follwers are often used just before the EQ circuits in many high gain, "British" sounding amps), phase splitters, etc. All you have to do is simply plug in various resistors and capacitors. Copeland also makes a cap mod board that can filter out the ripple of up to 800 volts. Great for quick design power supplies. They don't yet make a tube preamp kit ( low weight, high voltage (350-450 volts, 10-20 milliamps) transformer, 4 or 5 tube mod boards, cap mod board, chassis, etc ), but they might if enough people write and ask them to. Another good thing about Copeland is that they don't seem to hype their products like some other amp kit suppliers. They seem very straightforward. If you know of any other amp part/kit suppliers, please post the addresses here and/or e-mail them to me. I'm having a hard time finding transformers designed expressly for tube preamp use ( high voltage, low current for B+, and DC voltage for tube hear ) I do NOT want to use big, heavy, expansive amp transformers. Thanks. McJimi
