This Amplifier is ,some Audiophile from end of Europa thinking order in future.he said may I use both of 45 and 300B can be use by bunch of switch,
schematic is shown above, 2 of switch can use each other of valves. 45 and 300B. amplifier is using ,,suppose be use FC-20S ISO Transformer universal
audio transformer.just show in circuit diagram. 45 is 1.6 W and 300B is 8 W rms max.out put impedance are 8 and 16 ohms.
NFB is overall 6dB and Non NFB.45 is 5K ohm of plate impedance and 3.5 K ohms for 300B.replace by one of switch selector at secondary.
Still this is only one of idea of an Amplifier compatible 45 and 300B.
