Started building the new 5E3 ceriatone this weekend, realised that I will need to bias the tubes after its complete. When I built the JTM I fitted a 1ohm resistor between pins 1 and 8 then down to earth, then with the KT66's in place measured the voltage at pin 8 when the amp was idle, because the resistor is 1 ohm the voltage reading is the same as the current.

My question is can I do something similar with the 5E3 valves (6V6)

Thanks

... but stock 5E3 is cathode-biased amp.  Huh?

No need to bias the amp.
