Help with a 33" tube ID

[Arm123]

I’m trying to find the heater value for this tube, so i can test / rejuv it.

Anyone recognize it ?

The chassis that was on it was Kortek KT-3301

I cant seem to find any combination of those numbers, in my bk setup chart (August 1999 Edition).  Anyone have an updated copy of the setup chart ?

don't have a number for ya , but try pins 9,10 for filaments
and the rest may be

5  g1
6  green cathode
7  g2
8   red cathode
9   fil
10 fil
11 blue cathode

thanks for the reply qrz   

Im just worried about getting the heater and G1 voltages wrong.  I was thinking of just using the most common values H 6.3v , G1 50v  What kind of damage would that do ?

Try searching for the same number but start it with an A.80EEF..... The B in front indicates it is a B grade tube. A lot of my competition do this. one of the biggest reason I get beat out on pricing.
Based on the "red" coating on the back of the tube instead of Grey, likely made in the North America...nope in fact positive it is a Phillips "B" Grade tube, likely Totoku yoke.

Hope this helps and good luck.

Its definetly manufactured in the US.

Thanks very much for the info Rick   

[edit]
did some searching, only results i found were making reference to a Phillips tube.  So your right.

Turns out that i tried to test the tube and the R, B guns were in the bad and the G gun was dead.  I tried to rejuvenate the guns and the R + B guns moved up a bit but the G moved a hair but was still close to dead.  So this tube is dead !

So sad.
