S/C model #200 PA amp, late '40's early 1950's I think. It has huge transformers and 2 6L6 power tubes for about 25 watts output. Recent service with grounded AC cord., RCA type inputs for a line level signal like a CD/MP3 player, and high impedance 1/4" Mic inputs which work well for guitar, as well as standaed 1/4" speaker output jack(8 ohm) added. Excellent working vintage tube head for guiitar or harp. This ad was posted with the http://info.kijiji.ca/ios .
