Hello Leigh,

Yes - 100% certain on this. I speak with the production people at CPI / 
Eimac often on the phone. I also know one of the engineers there. Also, 
the packing lists I receive from Eimac with tube shipments states 
"Country of Origin: USA".

The rationale was simple really - much of the sheet metal and tube 
sockets, etc were designed around the 3CPX800A7, so it would be a big 
step backwards to change now - plus I have over 130 new tubes at the 
moment. Also my account terms with Eimac limit me to only purchasing the 
3CPX800A7 tube factory-direct, so I'd have to pay a higher price from a 
dealer to go with the 8877. But I do agree the 8877 is pretty attractive.
