Not that there are any scratches, dings or dents but just because they are not new I have rated them near mint otherwise they are in mint condition. They're stable, well constructed with top materials and wiring. Power tubes are military spec Jan 6384 Tung-Sol power tubes still test new even after many hrs. We have been using various 5963 pre-amplifier tubes, rolling other various black and grey plate 12ax7's, 12au7wa's, 12at7's and 5814A tubes switching. 6AR6 tubes can also be used in place of the 6384's without any adjustments, 6L6 variants can be used with the use of socket adapters and will yield more power.
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 high quality wring, the vintage (new, never used until the install) 1949-50 Western Electric Teflon insulted pure silver core with high quality tight silver mesh signal wire used for board casting music-intercom system throughout 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. There are two amps to package. Best to send in separate boxes. Please wait for an invoice to be sent.
