[Test-Equipment] Questions about a I-111 tube tester

[jeremy-ca]

I picked one up yesterday and wonder about suggestions, changes or whatever 
before I plug it in.

A google search turns up very little info and nothing on calibration or 
parts that should be changed to bring it into spec.

It is made by Hickock and appears untouched inside. Everything is coated 
with the "tropicalizing" coating. The settings booklet is a later issue and 
covers thru the B model. The original model plate is missing.

I plan to use it for early type tubes and dont need the adapter kit.
