That's what struck me!
Back then, the pair of output tubes ($5) would be more than the power
transformer! But, half the price of the output transformers.
If I were to guess - the assembly of the 6L6 was probably highly
automated early on - with tooling design specifically to crank out this
tube accurately in high volume at lower prices, to facilitate sales volume
of more affordable products..
The 6B4 - however, I bet was still subject to hand assembly, keeping the price high... Maybe (we dont know!) the early 6L6 didnt last long in circuit, so perhaps the earlier generation of DHTs was thought to be better solely because of it's longevity in the socket. Who knows!
