Good Sunday everyone,
How possible is it to use a 6AS7 to drive a sweep tube P-P? The 6AS7 would be “driven” from a phase inverter.
With retirement coming up in 2 months, I’m planning my anti-boredom activities!
Thanks,
Ray

A common sweep tube don´t need such a driver. In my 6JN6 OTL experiment, I use another compactron tube to drive them in Class A. Only about 20~22V are needed in the vast majority of them. In any case a 12AX7 suffices.
I drive my sweep tubes (and basically all others) with a 6SN7. The 6AS7 could be used, but the gain is so low you'll basically have insertion loss instead of gain.
You might want to try using that tube.
It may sound quite, like you would like.
People have been using them for many years.
And not just for electronic scales ......

How are you using the finals? Pseudotriode, pentode, or screen driven? Class AB1 pentodes aren't a hard load and 6AS7s would be overkill. Pseudotriode would be a bit harder. 6SN7 cathode followers would get the job done just fine. It would be a different story if using screen drive. You could use a 6AS7 for that, though a source follower would be better.
