I am selling a pair of custom built (by a professional), high-quality pair of Two-Chassis 2A3 Tube Mono Amplifiers. Each channel has UTC LS-55 Output Transformer, with 2 pieces of 2A3 tubes and 2 pieces of 6SN7 GTB drivers. Each channel has its own outboard power supply. Point-to-point wiring.

They are push-pull, has tube rectifier with chock. See the pictures. I am not sure about the power output. I'd say something like 15-20w. I actually have a single piece of Brook 12A which gets 12W and smaller output transformer.

These mono block Tube Amps are in great working condition. They produce wonderful music. I don't have schematic. The cord from power supply to the amp needs some fixing to secure the cable. I am not good at that. So, I leave to the new owner.


I welcome local cash transaction. I also know how to pack for safe shipping. Paypal for distant buyer is OK, but please add 3% (international will be 5%). Domestic shipping in a single box but in two boxes for international shipping due to weight limit.

Questions for the seller
The measured wattage?
Not 100% sure but probably about 15 -20 watt.
