I'm interested in knowing the general answer for any of the tubes. In 
specific I have a pair of 3PCX800A7 I bought when I had my Ten-Tec 
Titan and they were full output tubes. With the thought I may get an 
amp that uses them, I've kept them on a shelf but sold the amp. I 
also have a spare 3CPX1500A7 for the AL-1500 and that's at least a 
tube I can put in a rig. 

I have an Astron variable volt and amp PS which can be used to hook 
up the 3CPX800's to let them warm up for a period, if that would be 
of help. If not, I don't want to bother.
