Punk--
1. When output tubes can be biased separately, 'matched' tubes are NOT required for excellent performance.
2. Are you sure your 'Canes can use '34s? I don't recall seeing that in my manual.
3. You do NOT need a tubetester. The WORST thing that will happen is one tube you install will be shorted or will arc and blow the high-Voltage fuse. (You DO have spare fuses--both kinds--don't you?)
4. Heed the instructions when replacing output tubes--the bias pot for that tube should be turned full down...CLOCKWISE, not counterclockwise...before you turn the amp back on. Turn the bias-selector switch to that tube, turn the bias meter on, and then adjust that tube's bias after the high-Voltage relay closes and the bias amount sort of settles. You probably already know that the tubes' bias draws vary considerably from cold to hot; if I've not moved my amp(s), I adjust mine before I turn the amps off for the evening.
5. 'Matched' output tubes are very close in bias draw, so that they'll work correctly in amps without separate bias adustments per tube.
Enjoy your 'Canes; I sure enjoy mine. I just finished my improvements; see my system.
Do you use yours in UL or triode? What do you drive with them?
PS. It's 'pentode'.
