Amps are cathode biased with on board Alps carbon pots for a very minimalist approach (no need for an external pre-amplifier). They never seem to lose full power. The TO-300's sound great.
Note the vintage (new, never used until the install), 1949-50 Western Electric high purity silver core Teflon insulated w/a outer high purity silver insulated mesh used in broadcasting music-signal wire intercom system in select Bell telephone company buildings. Cost was never a consideration back then. They produced the very best wires and cables for Bell and other companies. Some vintage Western Electric wiring are considered the best for use in tube audio equipment; pre-amps, tube amplifiers and such.
20/20 wpc using various 5963 tubes and there substitutes. 4, 8, and 16 ohm taps inside. If you want to control the volume up and down, switch to a CD player, a recorder, tuner, tv, or monitors it's nice to have another pre-amplifier for switching.
We have been using an Oppo 105 3D Blue ray player as a pre-amplifier for total switching control. I intend to set price very reasonable for this pair of mono blocks.
Make me a reasonable offer. Is it punks or isn't it?
