Re: WARNING ON 6SL7 AND 12SL7 SUBSTITUTIONS


Hi Al,

Thanks for helping clean up the mess we started here. It is true we are dealing with multiple variables on this CCS topic, so it does get confusing.

Your warning is valid, but I do have a question:
Do you have an understanding of what risks one is taking by running a *SL7 tube with positive grid current? Shortened tube life? Something worse?

Thank you!

Paul Speltz
