Original GM3SEK/G3SEK Tetrode Boards
Boards are 95% assembled and configured for 4-250A tubes. If you plan on using different tetrode tubes, you'll need to do the math outlined in the printed manual I'm including. Includes R14 wire-wound adjustable resistor, heatsinks & mounting hardware for TO220 transistors, off-board connectors, 500-ohm wire-wound pot, 5k 50W chassis mount resistor, remaining discrete components, and Stancor P-8671 117V 50-60hz/36v/1A transformer. I can provide photos of the boards. I am asking $550 + Shipping. Send your zip code, and I'll calculate the final cost. I prefer Zelle/Venmo and USPS money orders, too. No PayPal. All items are sold as-is with no returns. 73! Mark KA6WKE - DM34st Website: Youtube: Amateur Radio: LinkedIn:? |
开云体育Are there more than one set of boards: i.e., are you selling multiple sets of boards for multiple amplifiers?? Or is this just one amplifier-set of boards? TNX, Steve K0XP
