Vintage Tube Amp

Vintage Ampex A620 Portable Amplifier. Very nice cosmetic condition.

Vintage Ampex A620 Portable Amplifier. Very nice cosmetic condition. Tried a microphone for input. Output was low, but it did work.

The empty octal socket on the chassis is likely for a plug-in type transformer. Further research and reverse engineering of the wiring may help yield a better idea of what this unit was used for. There is wear from use/storage like scratches, scuffs and dust. Comes with one Jones plug and tubes. 2 x General Electric 12AX7. 1 x RCA 6AQ5. 1 x General Electric 6X4. Please contact me if you have any questions.

For sale Ampex 620 amplifier, came from suitcase amps. Made in the mid 1950s, it’s have hum noise from filter capacitor, before use, need replace some parts.

This is for the pair of Ampex 6L6 amplifiers as shown. They do not include any tubes and will need tubes. One of the amps appears to have had the capacitors replaced and a wire cut from the switch and the fuse. I’m not sure if this has been bypassed for some reason and perhaps that’s why this was done. See photos for details. Physical addresses only no PO or apo boxes.

The speaker works and sounds good, the amp is untested and I don’t know if it is working or not. Could be a good restoration project for someone, or use it for parts. See photos for details. Physical addresses only no PO or apo boxes.

Vintage 1950′s AMPEX A692 Amplifier loudspeaker Works. Plugged in bass guitar and it works. Probably could use a cleaning since its been stored away for years. The case is a little dirty too. Comes with original power cord. Cord shows its age but does power it on. Rare and harder to come by amplifier. Very sought after for the incredible sound. Will be double boxed and it is heavy.

Vintage Ampex Stereo Amplifier. Inherited from a family member. Plugged it in, light turned on. I have no clue whether or not it is working or unworking.

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.
