Ampex Model 620 powered amplifier-speaker monitor I have used for years. Sometimes in my studio and sometimes in remote recordings. It has a JBL speakers and both units are in very good condition all original with power cables. I did recap it about 11 or 12 years ago.

When closed, the case measures approximately 17 x 14 x 8 1/2 inches and weighs about 24 pounds. This item is listed in multiple sites as well as locally.

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.
