Greetings,
Kindly allow me to ask for assistance regarding a very loosely related question. I just acquired a 57 year old Shell Test-O-Matic tube tester for a young friend who restores old trucks and is learning how to repair and rebuild the original AM radios.
The tube tester has a lid mounted ¡°set-up¡± chart dated June 1958, mostly in legible condition.
Does anyone have additional or supplemental tube test charts for this generation of Test-O-Matic tube tester you are willing to share, copy, or sell?
Thanks very much for your time and bandwidth.
Regards,
Ken
