Heater voltages

[timmy]

Yes the pilot, 4 - 6au6 in a row and switched around and now it changed low voltage on another one so I guess it's difference in resistance between tubes but I hope at 5 vac there is enough for the tube to conduct.

Does the low voltage occur on the same tube independent of which socket it is plugged into, or is the voltage always low at a particular socket no matter which tube you plug into it?
