Dukane 1A775C tube mono amplifier pair puse-pull parallel in great working

For more information you can go search in the web Audiokarma dot org. This pair of Dukane 1A775C mono tube amplifiers are in great working conditions. They are my long term collections and I think they are more powerful thank 1A475C because they use quad 8471 tubes for each mono amplifier in push-pull parallel.

One of this mono amplifier has its high voltages can capacitors updated with new caps. These pair of Dukane 1A775 are very close to McIntosh P-153, Quick Silver 8417 mono amplifier, and Bogen MO-100A and have more stable design since they were designed for industrial use with 19 inches rack mount. The inputs and outputs connections are both provided with the RCA input and banana plugs outputs connections.

Also AC connectors for both mono amplifiers are provided. Besides, you can find the schematic diagram from the website if you need to service them.
