Vintage Tube Amp

Offered is a vintage homemade tube amplifier. Has some wear, see pictures. Please contact with any questions regarding item.

I believe it’s a tube amplifier. See all photos for condition and what’s all included.

THIS COMES AS PICTURED AND UNTESTED. I BELIEVE IT IS A 2-CHANNEL POWER SUPPLY BUT THE PARTS IN IT ARE VERY NICE AND COULD BE USED IN AN AMPLIFIER BUILD.

For those satisfied with nothing but the ultimate in High-Fidelity. It’s the McIntosh 50 watt amplifier – unsurpassed for performance and quality McIntosh 50W2 Monaural Power Amplifier & P50D Power Supply – This listings is for two sets of the highly regarded McIntosh 50W2 Amplifier. Each amplifier and power supply has been tested for power only, all power on, no further testing was done. On one of the power supplies the mounts for 2 capacitors have broken off, still works, see photo. Serial number have faded on 3 of the 4 units, with only one completely visible reading 3153. Please message me with any questions, thank you.

7199 tested very close to new. Selenium diode has been replaced with a new production 600V volt rated bridge diode (Digikey). This amplifier uses the 7199 tubes and can use 7189 or EL84 6BQ5 output tubes.

Not sure what this is for. Found a bunch of ampex gear in a storage unit. Been in storage for 31 years. Please see pictures for condition as they are part of description.
