Here are a few of our circuit designs. We are more than happy to incorporate these designs when we  build your amp or pre-amplifier.
 
Construct these schematics at your own risk. Vacuum tube electronics possess high voltages and high temperatures that can harm you. Different amps and preamps require different levels experience from the builder with some projects needing only a multi-meter and others needing more sophisticated equipment to assist the builder. Have a look at circuits listed to the left.
 
Electra-Print Audio is more than happy to supply you with all the power transformers, output transformers, interstage transformers and chokes you will need for these projects. Please contact us.
