Following the great tips from PRR and others I decided to check out some remote cut-off tubes and share the results.
test conditions: Used a copy of the Fairchild 240V regulated supply with 10k on the plates and 100 ohms on the cathodes and all the pentodes wired as triodes. Sig Gen 600 ohm source with 500mV on Vg1
The results show how linear the 6BA6 is, after the kink, compared to the other tubes that have been mentioned in the threads.
This is my first try at posting a link....hope it works http://i39.tinypic.com/15zpg5w.jpg
I'd be interested to get some feedback even if its negative!
