Good morning everyone,
So, out of curiosity I checked the individual plate current on a set of 6LX6's in P-P, one tube was at 43 ma, the other was at 24 ma. Obviously not a good situation. I put a set of 6LB6's in and the difference was only 1 ma. So, the question is do I have a bad 6LX6 or is that a normal spread for sweep tubes?
Thanks,
Ray

I'd say so. The only time I saw 6BQ6s (another type of sweep tube) with currents that far off, it was due to gassiness. Current shouldn't run away like that for any type of VT.
