How many mA or mV do you like to see on your EL34 tubes?

[baretta]

Per tube.

 

[Dave451]

50-55 mA per tube on my Scott 272.

 

[Brice]

We need the plate voltage, or the amp model, or the schematic, else it means nothing.

First, the mV is a voltage produced by a current sense resistor. Its value matters. A 10 Ohm will show 1V for a 100 mA idle, Ohm's Law will tell the tale for any other value...

Voltage is as Douglas said, current will depend on the voltage and conditions. A lot of them seem to run somewhere in the ballpark of 50ma per tube, but datasheet conditions do actually call for higher in many cases.

 

[JohnT123]

I set them up around 20 watts dissipation at idle.

 

[TriodeLuvr]

The spec is 1.5A each.

[PakProtector]

The spec is 1.5A each.

That looks like a heater current number. Completely independent from the plate current.

[Pio1980]

45-50mA each in P/P.

It's as good an answer as any, considering the question.

 

[baretta]

Around 440 plate volts.

 

[JohnT123]

Right around 50 ma would be good.

 

[Brice]

Correct for cathode bias design.
For fixed bias it's around 40 -45mA

 

[Pio1980]

DG recommends 50 mA fixed bias for P/P, I run a bit less averaged for varying AC line voltage.

 

[gadget73]

The people at Mullard call for more than that in most cases, but again it depends on the conditions. Note that every configuration shows something different even at similar voltages.
