Electron tube
1.6.3V filament rectifier tube: 6Z5P, 6X5.
2.5V filament rectifier tube: 5R4, 5U4G, 5AR4, GZ33, GZ34274B, 5Y3, 5Z3P.
3.6.3V signal tube: 6N11, 6N1P, E88CC, E188CC, CCA, 6922, 6H23, 6H6, 6H30, (6SN7 requires a 6SN7 to 6922 adapter).
4.12.6V signal tube: 12AU7, 12BH7, E80CC, (12SN7 requires 6SN7 to 6922 conversion socket).
When using a 6.3V filament rectifier, the onboard S2 switch needs to be turned to the 6X5 position. When using a 5V filament rectifier, the onboard S2 switch needs to be turned to the 5AR4 position.
When using a 6.3V filament signal tube, the onboard S1 switch needs to be set to the 6.3V position. When using a 12.6V filament signal tube, the onboard S1 switch needs to be set to the 12.6V position.
