Here we have a vintage Supro guitar amplifier! This is an early Valco Chicago 51 model amp with dual inputs and a single volume control. It has a Jensen 10” speaker with 6V6 power tubes and puts out around 10 watts. The amp retains its original 2 prong power cable. We suggest service and installation of a grounded 3 prong cable for use. The amp is in good shape and good functioning order. It has a two tone gray and black wrap with a replacement leather handle. It’s cool to see such an early iteration!
