Details:

The ac cord appears to have been replaced in the past. I notice the needle movement speed seems normal when testing for mutual conductance tube test 1 or 2, but moves slow doing line adjustment. This seems to be testing higher than it should on most tubes and will likely need calibration get accurate results. This is packed good for a safe arrival !, photos of tube tests; both tests 5z4 rectifier, 6ea7, 6l6gc and the last test 6l6g known to have short.
