TT1... we found a 7591 in supplemental, its looking for a bias setting of 19g. He can set to L or H, but, no G.

Go for H, it's closer.

If he is using a Heathkit IT-17 tube tester, the Supplemental Test Data Sheet lists the 7591 as follows:
Type: 3
Fil.: 6.3
Plate: 20
Top: CDFH (D and H bold)
Bottom: EG (G bold)

The Howard W. Sams Tube Substitution Handbook No. 19 does not show an equivalent for the 7591.

Maybe this will help.

Send'em to me Ron, and I'll toss out the bad ones, and send you the good ones back.ara:

Similar but not plug-in replacements are the 6GM5 and the 7868. Both have different bases but the insides are much the same.

Hope that helps...

That setting pegs the meter

Jeff just left and although we couldn't find a "G" setting for bias, we fumbled by without blowing anything up

No drinks other than diet root beers and lemonade

Ron thanks for everything, that was great.

Folks I got to listen to Ron's Edgarhorns on 300b meshplates. It was a religious experience.

Self flagellation is also considered a religious experience in some circles
