Hoping someone in here wouldn't mind sharing some knowledge and advise on these questions and issues that I'm having.
I posted this in Vintage HiFi with no response yet:
Just got an old Sencore Mighty Mite TC114.
When setting up for individual tubes listed in the set up book there are several occasions where it lists 2 and sometimes 3 different settings for switch D which I think is only used for calibrating.
How do you know which setting to use for the most accurate test?
When reading the scale what unit of measure do the numbers represent? I guess a tube reading 95 is better than a tube reading 82 during an emission test but what does it mean?
When I zero the needle when off then calibrate for a tube the needle is no longer zero when turned back off. Am I screwing up some how or do I have a junk tester? I'm starting to think that the movement on the meters needle needs to be cleaned because after adjustments are made I can tap on the tester and get additional movement.
