DuKane Model 2A40A Mic Preamp / Mixer

Description

DuKane Model 2A40A Microphone Preamp-Mixer. The unit is in original condition. It looks to be complete and includes all tubes shown including (4) EF86 Amperex tubes which look very nice. Also included are the DuKane impedance matching transformers and the VU meter which plugs in on the chassis. All of the capacitors look to be original and likely need replacing. The power cord is brittle and has crumbling insulation. The unit is untested and is sold as-is for parts or repair. Buyer pays shipping in CONUS.
