This is a jewel of a pre-amp. The sound is exquisite. Warm, lush, yet so clear. This is a one person, one home unit that was not used for the last 20 years. All the tubes are original (super rare!) and very strong. It has benefited from a complete recap with 105°C Nichicon capacitors, all switches tone controls and contacts cleaned with Deoxit. Attenuator volume and balance control pots cleaned with 99% ethyl alcohol. The unit will be shipped with a 120v step down transformer as this is a tube domestic japan model (100v). Shipping is included in the asking price. No trades. Thank you!
