Two more 45 / 2A3 amplifiers finished. A two chassis amp (stereo with external PSU) using a directly heated driver tube, either a 26 or 10Y. And a single chassis amp with indirectly heated driver stage.
Both amps can be configured for using either a 45 or a 2A3 as output tube.
The two chassis amp uses Tango interstage and output transformers.
The PSU uses my usual bridge rectifier configuration with 4 6AX4 TV dampers working into a choke input filter.
The single chassis amp uses Lundahl interstage and output transformers.
This amp uses a bit simpler power supply with 2 6AX4 TV dampers.
The circuit is similar to the one of a 46 amplifier which I presented some time ago.
Some close up shots of the amps:
