Extra rare 45 tube amplifier, working in class A1 push pull. Output transformer is early Triad ones. max output 5W at 8ohm.

Perfect amplifier with power tube 45' and prestage tube 717A, driver tube is 6SN7. It is really amazing sound, I set it work at class A1 so output power is only 5W, instead of 15W if you let it work at class A2.

Sound is perfect, very rich, detail and musical. Walnut wooden case 36mm thick and 3mm of cooper top plate make item become quite good vintage one.

All tubes are not included.
