ZETA AMPS AND EFFECTS


RedHead
My first project in this series got named RedHead. Inspired by the Nano Head I decided to do something similar. It has a 6112 double triode as a preamptube in two gainstages, and then a 6021 as output tube in push-pull. It's powered by an external 12VDC adapter, which is internally converted to 165VDC. It has no semiconductors in the signalpath. I should add that it is not a clone of the Nano Head.
