Vintage very cool in working condition

All tubes power on and from what I can tell the functions work

however unclear how to use all the functions to get the right ssignals and send signals

Awesome piece for a collector!

RETURNS ARE NOT ACCEPTED BECAUSE YOUR TESTER SAYS SOMETHING DIFFERENT THAN MINE. If you don?t like the sound of a tube, so long as it is still in the same condition as arrived message me and I?ll work with you
