Hi,
Can anyone tell me the settings for bias to test 6DJ8 or 6922 on a Hickok 605A? Also what should the reading be? My tube chart doesn't have those tubes, nor the chart I downloaded from the web. A pointer to a newish tube chart, mine is 1957, on the web would also be appreciated.
One more question, are the Gm values given in the charts minimum goods or new tube values or what? They don't seem to mention that point in the manual, or I'm missing it.
Thanks,
Michael

Hi Mike,
I'm not familiar with your 605, but the given Gm numbers are usually always the minimum you should expect with Hickoks.

Hi Victor,
To further complicate matters I found a note on Hickok's that said that the smaller models (no list of numbers) give the value for a new tube and the bigger models like the 539 give the minimum value. I don't know if the 605A would be small or big.
They also mentioned that the 6DJ8 bias setting is wrong on most all the charts, but it gave the correct number as 24. Unfortunately they didn't mention what the reading should be. Sheesh.
