Wouldn't you know it, on the Steve Johnson site, he has updated roll chart data for the 752 he apparently received and posted, and it is missing the page(s) between 6D and 6H.
Anybody know the settings for 6AW8, 6GH8, and 6GW8? I have two each of the AW and GH, got the pin out and set the switches, started high on the bias and came down to an arbitrary meter reading and compared the tubes at the same settings and were very close, but only had one 6GW8, best I can do is that it does not take minimum bias to get a reading for both halves and it is not shorted. All of these are dual section, pentode/triode.
I looked at another Hickok tester he had listed with an updated chart, both about the same vintage, and that chart had the tubes, but the switches were not the same, so it appears who ever sent Steve the chart, skipped a page.

$10 and done.... https://www.ebay.com/itm/192687648365I have a 752A, with the added Novar and compactron sockets that the 752 lacks, unless the CA-4 is employed.
