Vintage 1950 MG-30-B Tube Amplifier Don McGohan Mcgohan Inc. Working
1950s Retro cool vintage McGohan MG-30B Tube PA Amplifier. The amp "works". Has all original 6 capacitors, tested the tubes, cleaned all controls and sockets. If you were going to utilize this everyday, I change at least the single paper cap inside. It’s got a great vintage hammertone look, and sounds beefy through a dual 12” cab I keep around the shop. Can be used with 4, 8, or 16 ohm cabinet. We replaced the original cord with a new a 3 prong grounded ac cord. Includes Sams Photofact Service Manual.

Inputs (4): 2 RCA (for phono Mag and XTL) and 2- 1/4” TS input jacks.
Outputs (2): 5 Pin (like a leslie speaker) Amphenol Connector. Speaker outputs on rear. Note: A dual .75" center to center banana plug or two banana plug will fit! The live pins are 3 and 9 o'clock position (see photo)
Controls Knobs (5): Bass (also AC On ) Treble, Phono 1 and 2 (see below), Mic 1
Note: The phono knob and control is a bit unique. In the 12 o'clock position marked "0" the phono stage gain is "0"or silent, moving the knob clockwise from "0" increases the gain for phono 2 (XTAL-Crystal Phono Input) and moving counterclockwise from "0" increases the gain for Phono1 (Mag Magnetic) Sort of like a dial mixer, but assuming you have two phono's attached.
Power Output 30 Watts (MG-30B)
