In the pipeline.............

A home built all valve 12w guitar amplifier. Built from a kit supplied by ampmaker.com I'm chasing the sound from my Fender Supersonic 22 but in a much smaller package and with a little less power.
I'm also modifying a Fender Frontman 15G guitar amp by converting the output stage to a bridged amplifier design to increase the power.
