• Notes

• This amplifier was targeted to the high-end/professional market in the USA, so it doesn't include a power switch and the power cable is captive. The power transformer is wired to 110VAC at 60Hz. Conversion to 220VAC is done internally by unsoldering/soldering the jumpers. Some units included a wood box as well.

  Specs: Output power 125W per channel on a 8ohm load and doubling the power at 4ohm load.
