 Post subject: Checking 4-pin tubes on a Superior TV-11 tester

I'm trying to test 4 old tubes that come out of a battery
operated radio, the Coronado 550. They are the 30, 32, 34 and 1-A-6 4-pin type tubes. My Mercury 2000 tester is too modern, the Superior tv-11 has a plug-in for 4-pin tubes, but does not contain the data on it's chart for those particular tubes. I actually ordered a Heathkit TC-1 to test the tubes on ( I knew the tube info was on their chart) but that tester apparently isn't functioning properly because the tubes don't even warm up.
How can I test the tubes on my Superior TV-11 without the proper
data? Is there some way to transpose the data from the Heathkit? Thanks for any help...

There is information for TW11 here. Maybe it's the same.

http://bama.edebris.com/manuals/

Check continuity of filaments on pin #1 and #4 of 30, 32 and 34. On a 1A6 it's pin #1 and #6.

These tubes will not warm up. They were made for battery operation and use low current. The filament can only been seen in a dark room.

Here is the info for the TV-11:

Code:
       Fil.                                 Fil.
Tube   Volts   F      N      P     Load     Cont.
----   -----  ---  -------  ---    ----     -----
  30    2.0    1             3       6       1,4
  32    2.0    1             TC      6       1,5
  34    2.0    1             TC      6       1,4
1A6    2.0    1             TC      6       1,6
1A6    2.0    1              4     10       1,6


This info is in the Jan. 1963 TV-11 supplement. I can scan the sheets and post them.


***Edit: I've scanned and uploaded the supplement. You can get it here:

Thank you for your direction. The data you provided gave me the means to test the tubes... 2 of the 5 are defective. New ones are on order... thanks again
