6V6 Operating point in Deluxe / Reverb AB763

[pdf64]

https://el34world.com/charts/Schematics/files/Fender/Fender_deluxe_reverb_ab763_schematic.pdf
The schematic notes the anodes are 415V, the screen grids will be within a volt of that, and the bias is -35V.
Using the triode connected chart on p4 of https://frank.pocnet.net/sheets/093/6/6V6GT.pdf seems to indicate that a bogie 6V6 would be passing about 33-34mA anode + screen grid current.
Have I got that right?
If so, the resulting 14W idle dissipation seems rather hot, is it better to assume that -
1/ Fender intended such a such hot bias
2/ the readings were taken using weak-ish 6V6 which required a lower than normal bias voltage
3/ measurement  / drafting error
4/ the bias had been set a bit hot accidentally
 
Thanks

Tubes in 1963 were considered a consumable that were expected to be periodically replaced. I remember buying tubes at the drug store in the late sixties. There was a tube tester on-site to test your tubes and replacements of common varieties were on hand. It should also be noted that amp manufacturers at that time were trying to get the last watt out of their circuits for advertising propaganda.
