RE: Actually

To be more specific, Tung Sol claimed that their control grids were gold-plated as far back as their 1950 description of the design of the 5881.

On their 1954 6550 advertisement, they claim, "Maximum control of grid emission achieved by gold plating and carbonizing."

As a Leslie amp tech, I always check for grid emission when servicing amps, and I find that the old Tung Sols are, in fact, surprisingly immune to grid emission problems, more so even than the GE 6550A.
