Nice tuner, I resurrected this one from the parts or repair auction. Had a failed power supply, a 2SC2320 was in pieces and the zeners were toast. It piqued my interest because of its serial number "00003". That in itself was enough to put in the time for repair..

early Charlie's aligned by Mr. Bongiorno. Mine was done by him too.
Most don't know how to tell which ones were done by him. If it had Rack handles he did, if not...it was after he left SUMO.

  The number I keep hearing is about the first 1500 units were JB aligned. When I was repairing this one I ran across the gentleman who had SN 0009. He helped me getting some of the voltages correct.
