Yet another variation using the classic Electra-Print DRD circuit. This time it is for the 2A3 tube. If you have stockpiled a lifetime supply of these tubes, you really must build yourself a pair of these amps. All reviews love the design, does not matter if its a 45, 2A3 or 300B, the sound is great. We can supply you the power supply schematic, it will be similar to other DRD designs. Advanced test equipment is suggested to tune this amplifier for best performance.
