Range Master with Voltage Inverter

From the vendor

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. Current options - PNP (positive ground supply): • Russian MП16Б or MП41A 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. Because we care, and no-one likes messing around with dedicated posi-ground supplies, this new version has the option of a voltage inverter. This magical doohickey will let you use those beautiful PNP transistors while still working on a daisy-chainable standard negative ground supply. This is optional - you can still wire it posi-ground or use a battery if you prefer. Board-mounted pot for minimal wiring and easy enclosure mounting. Multimeter recommended for optimal biasing, but it can be done by ear. 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. Knob is not included.
