Purchased as a kit and assembled by me (nicely done, if I do say so myself). Mint condition.
The model 0247 is a fully discrete headphone amplifier, with USB DAC digital input included. The amplifier is a neat circuit, fully complementary, Sziklai pair output stage, and diamond buffer input stage, with current mirrors to provide the gain.
It is connected for 100-120V but can be converted to 200-240V by changing the wiring. It is stock except I changed the line output to feed from after the volume control (passive preamp connection) instead of in parallel with the headphone load (active preamplifier connection).

Price is negotiable, the kit cost me about 58,000 yen, but the price fully assembled is over 90,000 yen I think. Asking $600 US including shipping.
