Vintage Tube Amp

Vintage Hammond H-AO-33-1 tube amplifier. Taken from a working unit, cosmetically in good shape – a few inside components appear corroded but mostly clean (see photos).

These were pulled from vintage equipment, have drifted in value, and show some DC leakage. As such they are being listed as not working even though they still might be usable in lower voltage applications. I randomly measured exactly a third of them (20 out of the 60) with my Fluke DMM, and the average value reading was 0.136mfd. These all came from the same source so it’s likely the others will measure around that same range.

1950s Collins 356B high gain tube preamp or program / monitor amplifier. Same circuit as the Langevin 117a. The original, excellent, ADC transformers are guaranteed but this unit has been untested and the original capacitors must be replaced before applying power. Fantastic preamp for high gain use (ribbon mics, etc) once restored. Datasheet, schematics and test harness included. Tubes included but untested.

Vintage Early 1950′s Newcomb 6 Watt Amplifier Great For A Harp Player or Guitar player. Vintage early 1950′s Newcomb 6 Watt Amplifier in excellent condition. This fine amp sounds wonderful with an electric guitar or harmonica! This amp comes from a collector, which explains the excellent condition. All said, this is a great vintage amp looking for a guitar or Harp player!

The unit still powers up, and the turntable functions on all speeds. The only problem is when it’s switched all the way over 78, the turntable makes a scraping sound. I’m not sure if it’s missing anything for the tone arm rest. It could be similar to some of the guitar amplifiers they made. It’s in pretty good cosmetic condition, as you can see. There is one wear paint spot on the left bottom side. Otherwise, it’s in very good condition. I imagine this could be converted to a fine guitar amplifier.

Could be converted into a cool little tube hifi amplifier/receiver. Shows signs of use and wear but should clean up okay.

These are super nice. Plugged in a bluetooth receiver into the aux ports, and away she went. Sounded amazing, tight, clean etc. Turning the loudness back on it just a little evened it out. I cleaned it up a bit, was a bit dirty.

Home built vintage tube amplifier.

The Amp is a beast very heavy, it is based on the KT88 Tube and had 2 of them in it when found but has 4 Kt88 sockets. We are NOT including the KT88 tubes, all other tubes are included as shown.
