Tubes Asylum

Is there is test data for a 6B4G on an Eico 666 tester?

If you don't have it on that,he also has a Superior TW-11 tester.This is a friend of mine form Fla and that's what he has for testers.
Does anyone have the data for either of those testers for a 6B4G?

Honest amplification is better than excessive 2nd order distortion anytime.

I tested several 6B4Gs on my Eico 666 using data from Coletronics chart and they all tested short on the same pin, leading me to believe the data is wrong; wouldn't be the first time. They can't all be short. Meanwhile, the tubes sit in unresolved status.

  Direct heated tubes will test shorted for the heater/filament.

    The test settings should account for that. By chance I found some completely different settings that seem to be correct, 'obsolete tube' data for Eico 666. Of 3 6B4's -- 2 tubes good, one a little low.
    6.3. 7 75, 12315 11111, 4 1, 3-5, test on 3.

      Thankfully it isn't my tester.

      I'm glad you worked it out.
      
      On my Triplett 3444 all direct heated tube show a short, heater to cathode, because they're one in the same.
      
      But all testers are different.

He tested them as a 6B4 and they came out fine.

The 6B4 setting for the 666 (at least the one I have) appears to be the one you are looking for, as it corresponds to the 2A3 (other than Vf and pins of course).

Don't know if this helps but the roll chart for an Eico 667 (not 666) shows test data for a 6B4 (not 6B4G)

  Chris also found the 6B4 and was asking me and I told him I wasn't sure but now that you mention it,maybe I can compare it on a tester that lists both tubes and see if data is similar.You would think those early 60s testers would list those tubes.
