In this video:
I put the final touches to servicing a Sencor TC109 MiGHTY MiTE tube checker. This video focuses on replacing the selenium rectifier with a modern 1n4007 diode and determining the appropriate circuit resistance due to adding a more efficient silicon diode.
As mentioned a more thorough repair was done by @CharlieTechie with the exception of the rectifier. You can watch his video at the link below:
