Power tubes are direct coupled with no capacitors in the signal path. Film capacitors in the circuit are a power supply decoupling cap for a series regulator to reduce ripple and therefore noise..

quality components used in the build including Magnaquest Cobalt output transformer, V cap and Mundorf caps used.

Amps and tubes have been checked to be in very sound condition and ready for a new appreciative owner. Amps have that single ended purity and sound very well balanced and musical.


This a very affordable way to taste some single ended 2A3 or 45 tube magic for owners of efficient speakers.

I had the pleasure to listen to them hooked up to efficient full range speaker and I was blown away by how musical they are.

Firm lows and just beautiful mid range.

They would not disappoint that is for sure.
