That definitely could be the case. I've had ONE case of the 6V6GTs acting up in all the years I've had them. And many have been used at 425 -450 volts. But it can happen... Hopefully the vendor will stand behind yours!
Follow Ups:
Al, on many Fender amps... changing the screen resistors to wire wound or metal oxide, 5-watt 1k-ohm usually helps stabilize the output tubes.
My DR runs over 450VDC on the plates. I bias them to about 20mA per tube.
Photo is of my Super Reverb, I put 1k-ohm bricks onto the screen grids.
Good luck!
