Condition
These are very nice working generators and supply sufficient voltage output to directly couple to tube amplifier stages. Shown in the picture is its sinewave output on the oscilloscope … the square wave looks clean also. These units are original. Tested and all functions work properly.
They are nice and clean inside. The exteriors are in nice condition … they have a few scratches and marrs. Overall, they are nice clean units. A copy of the schematic is included. Guaranteed not to be DOA.
