[Amps] Testing a pair of 3CPX800A7's

[Kevin LaHaie]

I have a pair of 3CPX800A7's pulls, purchased with claimed 'full 
output', and I have no reason to doubt it, equally no reason to believe it!

I recently acquired an Alpha 89 amplifier, which uses the non pulse 
rated version of these tubes.

Alpha, of course, would warn against putting ANYTHING in their amps that 
was not procured from them.  something about hand selected tubes with 
low grid dissapation?  I have also heard (urban legend??) that there is 
a good possibility of serious damage to the amp should you not heed 
their warnings!

Therefore, I would love the reflector's collective wisdom to the 
question: Is there any valid reason not to use the Alpha 89 to test 
these tubes?

Thanks in advance for your comments!
