This is a very early 502A. It has no variable channel gain controls, nor a variable timebase control. It came this way from the factory. It is painted a lovely pearl grey color with new black handles. It has a new crt.
This unit has been completely restore both mechanically and electronically, including new paint and handles. It has been full calibrated and tested using our 72 hour burn-in process followed by recalibration. It is covered bumper-to-bumper by our 1 year warranty (3 months on the crt) and you are also protected by our 30-day return plan for repair or exchange. Who ever heard of anyone selling these with 30 day return, plus warranty? Not until now, that's for sure. I also carry a full line of new and used replacement parts as well as crt's for this unit.
