Harmony Model E-6663 Amplifier |
|||
This striking black and silver Harmony E-6663 amplifier was built by the Harmony Co. of Chicago for use with their lap steel guitars, circa 1940. It measures about 15 by 12 inches, and about 8 inches deep. The 8 inch speaker was driven by a pair of 6F6's, and two 6N7's took care of the low level amplification. | |||
