ETO Alpha 76A HF Amplifier

Unit is in excellent condition. It was purchase from a \"silent key\" estate sale. Executor stated the it had very little use. It\'s wired for 220-250V but can be wired for 110-130V. The unit looks\"brand new\"like it was just taken out of the box, but is sold \"as is\" due to it\'s age. I have no way to test the unit.
