You miss the point. Drake didn't buy their tubes from the surplus market.
They bought them bulk packaged from the manufacturer. It did make sence
from their standpoint and it didn't compromise the product. From a
boatanchor standpoint I wish they had used 6146's. But when put in their
shoes in 1963, it was a good business decision.

Most horizontal output tubes have distortion products comparable to the
6146 if you keep the voltage and power down to reasonable levels. Third
order products are typically in the -25 Db range which is right in there
with the 6146.

Another point of view: If a ham needed new final tubes he could buy
them at any TV shop or parts house, but the 6146 wasn't always available
over the counter without a wait.
