Webster Electric 5122A Tube Amplifier Chassis 2A3 Hammond Tone Cabinet Amp

This appears to be a Webster Electric Co. amplifier, with the inside tag showing No. 507 / Type 5122A / 60 cycles / 115 volts, and the tube socket layout matches the old 2A3 Hammond tone cabinet / organ amp style units people discuss online. A forum thread identifying this exact Webster 5122A says these were likely used as Hammond organ “tone amps” and describes the tube complement as four 2A3, two 56, and one 5Z3, which matches your socket markings.

Based on those comps, your tagged Type 5122A example looks stronger than a generic unmarked chassis, but it is still untested and incomplete without tubes.

Description
Vintage Webster Electric Co. tube amplifier chassis, tagged No. 507 / Type 5122A, made in Racine, Wisconsin, U.S.A.

This is an early mono amplifier chassis that appears to be one of the old Webster/Hammond tone cabinet style amps. The ID tag shows Type 5122A, 115 volts, and 60 cycles. Socket markings visible on the chassis include 5Z3, 2A3, and 56 positions. From the layout, this appears to be the desirable 4x 2A3 / 2x 56 / 1x 5Z3 type chassis.

Condition is untested. I have not powered it up or attempted any restoration. It is being sold exactly as found. Cosmetically it shows age, scuffs, paint loss, surface rust, and general wear from age and storage. Please study all photos carefully for condition and completeness.

The bottom is open and the internal components are visible. This is a good candidate for restoration, display, parts, or a vintage audio project.

Only what is shown is included. No tubes are included.

Due to the age of this equipment, it should be inspected and serviced by a qualified technician before use. As with most vintage tube equipment, some level of repair or restoration should be expected.
