The circuit is built out with Pete Millett's Jonokuchi PCB. Premium parts are used in the construction, and this unit has DC heaters for reduced noise and another tweak for the headphone output for silent operation.This amplifier features the 6EM7 dissimilar double triode that was originally intended for television use, but has lately found great favor in the audio community. The small half of the 6EM7 is much like half of a 12AX7 triode, while the output section is similar to an indirectly heated 2A3 triode. The chassis is machined and engraved copper, and I let it patina a bit to give the letters coloring, then cleaned up the top surface and sealed it with a polyurethane lacquer. The circuit employs some nice tricks from Pete, while using nice transformers of well above-average quality. This amplifier will power speakers with about 3 watts per channel, so those of you with high efficiency Klipsch speakers will enjoy this feature. The headphone/speaker outputs are switchable via a button on the front panel, and there is one input on the back of the amplifier (RCA) and one on the front (1/8" mini) selectable by a similar toggle switch. $500.
