Ron Wagner <[EMAIL PROTECTED]> made an utterance to the drakelist gang

Basically the "standard" substitutes are going to be problems. Even
some 6JB6s are issues. Try this link for discussion of issues with
neutralizing "off brands and subs"

All that said, the critical issue with life on the 6JB6s is to not key
down long while tuning, and as someone else suggested making sure you are
correctly tuned on the PA (aka resonated the tank). If you run twins have
a look at my post on "a kind to finals tune up" here
http://www.mail-archive.com/[email protected]/msg03471.html
And the book "A family affair" about the RL Drake compay has a good
discussion on test done.
Good luck, and hope this data helps.
73,
Ron

these? Are they a good sustitue or not? Do they physically fit in the RF cage?
