[NJARC] Oh no not the eye

[NICHOLAS SENKER]

Ray, I forgot to pick up one of your handout sheets; my question was what was the point of building a radio with all eye tubes, especially when only one fuctions as an eye tube?  Was it just to see if it could be done?  It would be nice to see the other tubes respond to audio, etc.

Many of you saw the Ruhf 6U5 superhet at the last club meeting that uses 
18 eye tubes as amplifiers.  Thought came to mind, - - since they are 
not used as "eye" tubes and do not glow maybe they would function well 
in a conventional eye tube application.  By the same token, I have a 
small box of  eye tubes that are very dim but maybe the amplifier 
section of the tube is still OK since I believe that they go dim when 
the coating on the anode dissipates or whatever.  Maybe I need a special 
tube tester setup to just check the amplifier function.  Guess the first 
step is to check the condition of the 18 tubes in the Ruhf radio.  Have 
not looked at the tube tester settings for the 6U5/6E5 or what the specs 
are for the tube.  Maybe there is a use for dim eye tubes and maybe 
those 18 tubes in the Ruhf radio can brighten some other radios.  Comments?
Ray
