Current stock:
0
These amplifier are in beautiful condition inside and out. They have been upgraded and overhauled from top to bottom and are guaranteed to the BEST sounding amplification you can find at this price... period. They have been professionally overhauled - permanently converted to mono operation, Van Den Hul wiring, gold-plated connectors, new power switches and audiophile sorbothane feet installed. Everything about these amplifier is top-notch and audiophile-grade. You will not be disappointed in the performance of these - guaranteed.
Original Owner's manuals included.
Cosmetic condition is near mint - They look nearly new. I can not find any blemishes. These were treasured by the previous owner. See photos for details.
