From the vendor
NEW VERSION IS AVAILABLE - This version has been retired. The Dallas Range Master. Bedrock of so many classic tones. Beautiful germanium treble boost. The originals used OC44 transistors, but they're as rare as a coat on a night out in Newcastle, so we'll offer a selection of cans as and when we have them available. They'll all offer their own unique character to this little gem, so why not try a few to see which you prefer? Now also availalble with no transistor in case you've sourced your own little beauty. PNP (positive ground supply): • 2N404 • AC128 If you can source a NPN transistor with low enough leakage you can make yourself a negative-ground version, but here at FDHQ we're all out. Board-mounted pot for minimal wiring and easy enclosure mounting. Multimeter recommended for optimal biasing, but it can be done by ear. Combine with a Power Pump kit if you want to power your PNP configuration on your standard polarity daisy chain. If you want the PCB without parts there's a link for that at the bottom of the page. Partial kit: PCB, all board-mounted components, pots. Full kit: As above, plus footswitch and appropriate daughterboard/components for your selected bypass type (see Downloads section for details of those), jack sockets, DC socket, battery snap, hook-up wire, LED. Enclosure (pre-drilled) is available as an option with full kits, and can take a battery if desired with footswitch positioned 22mm higher, closer to the controls. Knobs are not included. Inspired by: Range Master Difficulty: Easy PCB size: 30 x 22mm Knobs required: 1 Enclosure: 1590B Direct-Connect compatible (4-way) If you want the kit pre-built you must add the enclosure option below and select your knobs in the Components section. Check Specials for powder-coated enclosure availability. Download the INSTRUCTION PDF Here's the older version
