It is a nice clean well cared for unit. Its missing one bottom screw.Tested:I checked all tubes on a tester and they tested strong. I also treated all switches, pots and valve inserts with DeoXit cleaner lubricant. The unit powers on and goes into a standby mode for a couple of minutes, a green light flashes, then the light stops flashing, it stays lit and beautiful sound flowed through my speakers as provided in the video. The unit due to age, will most likely require restorative services.

If youve never heard one, you will be pleasantly surprised. Shipping will include handling and materials. No post office boxes and shipping to lower USA only please, and no shipping outside US.
