Vintage Tube Amp

This Heathkit EA-2 was tested with a MP3 player into the crystal cartridge input and it sounds great! Of course, it sounds better in person! You’ll notice when it’s turned off, it kind of fades away as the capacitors discharge and the tube filaments loose power! The filter caps have been changed as you can see. There are a couple mods done by the previous owner. One is the addition of an output jack for a recorder (see close up pic), the other are diodes on the 6X4? Tube socket so the tube is not necessary. Looks like all you have to do is remove the diodes and a tube can be used again (see close up pic). Cosmetically it’s very nice showing just some minor wear. It may or may not work at all when you get it!

Recheck 5 years ago. All vintage RCA tubes.

Turns on, lights up, all tubes light up, and produces a sweet warm sound. NOTE: Virtually all vintage tube amps require routine maintenance and servicing to operate reliably over time. At the time of testing, the unit fundamentally works, and all tubes are good. You will receive the exact unit shown. This will be packed with exquisite care. Please also feel free to message me if you have any questions.

Vintage Webster Electric 2A3 Mono Tube Amplifier Pair. Our testing only produced 1 watt for each amplifier. Also there is also an audible hum produced from the amplifier. The hum is in both amps, but one is a bit louder.

Sounds good being freshly recapped and new AC plug put on. GE and Westinghouse 6V6 Power tubes, RCA 5Y3 rectifier and three RCA 12ax7.

100% working, just had it tested and serviced. Very clean condition, aside from mismatched output tubes my tech says it has no issues, easy enough to switch out if you choose to.

From the home of a professional sound technician that worked in TV and radio in the 1950s, 60s, and 70s. It has a full compliment of tubes in the amp section, and the speaker for these units was apparently supplied by JBL. Please see pics, you will receive exactly what is shown. This unit has not been plugged in, powered on, or tested in anyway. It is ready to go to a proper technician that will test and power it up properly. Unit appears to be in very clean condition – abundant photos are provided. I was unable to determine whether this unit is a 620 or 622. There’s no identification tag on the unit, and it does not come with the original top cover of the suitcase cabinet. From what I read the 620 and 622 were virtually identical with just a few minor differences. The amp section, a 6V6 10 watt mono, was apparently identical in each model.

8 ROLA 6 ohm alnico magnet speaker tests good. All tubes included as pictured: (2) 35L6, 12AY7, 12SL7, and a 12AY7. I’m sure it will need at least new capacitors.

Speaker EIA code 285545. Includes everything pictured, speaker & mic with cables, but no power cord. Sorry No Exporting of this item. Not all sellers are created equal. Thanks for Looking and Good Luck.
