My Centurion (which I obtained used 20 years ago) finally had one of its 
tubes [rather spectacularly] go to the great beyond.

Unless I get really lucky and find a NOS pair at the e-place, it seems 
like my only other option is a matched pair from RF Parts.

Could you please elaborate a bit on your statement above that says "I've 
not had as good a luck with the current
Chinese-sourced tubes (specifically, the 3-500ZG's from RF Parts)".
