Beyond,
I own PL 6 mono amps.
I'm struggling to recall which output tube I settled on for the Cremonas since they ended up with the Pathos pretty quickly. The PL amps subtly, but clearly, change character as you swap output tubes - I suspect that the choice of output tube type is about as significant as the choice of amp model in the PL line. These days, I use KT66s when the PLs are on duty, but that tends to be with Merlin VSMs.
I'd suggest that you call Kevin Deal at Upscale Audio in Upland, Ca. He's a dealer for both SF and PL. He's a good guy and a straight shooter with long experience pairing up these brands.
Good Luck,
Marty
