12v dc to 22v step up, how do i build it ? Answered
planning to build a guitar amp that runs off a battery, need to get 22v to the plate.
can i build it to wire straight into the circuit? also where can i find a miniature output
transformer that can mix voltages and be suitable for audio use.
i want to build a 0.2w tube amp running at 8ohms off 12v and low amps.
