Cary 805 b & C or 211 amp


Cary owner please i need to know if the 805c or 211 amp by this manufacturer can take the Vaic 300b, 32b or 302b. Can i use the Vaic tubes on the Cary 805b or c?

The 300b tube on the Cary amp 805c or 211 is a driver tube, which is before the output tube of the 845 or 211 tube. Please advise? Your time are much appreciated!

300b tube on the Cary amp 805c or 211 is a driver tube
 No, the 300b is not the driver for the 805/211/845 tube, it's the driver for the inter-stage transformer which drives the above output tubes.

George... that was what i meant... sorry for the confusion.   Can the cary take the vaic, avvt or emission labs 32b, 320b tubes.  Please advise? 
Why not just use the Vaic, AVVT or EML 300B or 300B-XLS tubes?
