I believe this to be an Elenco Long Ranger Linear Amplifier model LR-1. It looks pretty good but it is untested. The tubes that came out of it are 5U4GB, AQ5A, and 4 x 6GK6 tubes all untested. The unit looks pretty good, needs dust cleaned off. It is fresh from an estate sale. Sine i do not know its electrical condition I am selling it as a FiXER UPPER or for PARTS. Be aware these units can HOLD A CHARGE, EVEN WHEN UNPLUGGED. Don’t mess with them if you dont know what you are doing?
