Hickok 539b switch settings for 6SL7

[famousmockingbird]

I have 6SN7 on my roll chart but no 6SL7. Should I use the 6SN7 settings? If anyone can find them on their roll chart let me know.

Thanks

Here is data from a Hickok 600 roll chart that I downloaded a few years back. I think these settings are the same as the 539 or at least they should be useful in determining how to translate 6SN7 settings for the 6SL7.

6SN7

6.3 JX - 4506 - 1 23 79 P4 2600 Triode 1

6.3 JX - 2103 - 5 23 79 P4 2600 Triode 2

6SL7

6.3 JX - 4506 - 1 7 58 P4 1250 Triode 1

6.3 JX - 2103 - 5 7 58 P4 1250 Triode 2

The Hickok 600 is not the same as the 539B/C. Here are the correct settings as listed in the Obsolete Supplementary Data.

Fil: 6.3V
Selectors: HY-4506-2 (triode 1)
Selectors: HY-1203-5 (triode 2)
Bias: 0.4V
Shunt: ---
Press: P4
Range: D
Min Mut Cond: 1000
