Important Note regarding Russian Preamp Tubes

Generally speaking; The filaments are virtually encased in the plate structure and when functioning properly they do not "light up" with the same brightness when compared to other tubes This is normal and not a problem. Unique spiral filament eliminates filament to cathode induced hum common on amps that use AC on the filaments.
