Both amps are setup for high power. The 300B's will run at 350V and 80mA.
The Lundahl OPT's are on order.
One amp will use a C3G in Triode mode for the input/driver, the other a 6SG7.
Before I list the amplifiers for sale, I listen to the each one for 10-20 hours, re-check the voltages, power output and frequency response.
The 3rd chassis will be used for an "A3 Series" amplifier.

The main power transformer is rated at 600mA. The amplifier draws about 250mA. So no need to worry about this bad boy being over loaded!
This is board supplies the DC voltage for the input/driver. Zener diodes are used for the "G2" voltage.
The 300B's use the "Ultra Path" configuration.
This is the "Hybrid Rectifier"
