Dave,

 Were are you located?  If you're in the US, and not too far from Texas,
 I'd be happy to test them for you.  Just send them to me, or if you're
 close enough, stop by, and I'll fire up the tube tester, and we can have 
 them finished in a short time.

                                             Regards,

                                               Jim
