Slew rate distortion in a 1970 Fender Vibrolux reverb.

The grid leak path is always between grid and cathode, no matter if actual grid voltage is positive, zero or negative and independent of how grid bias is produced.

As I'm not natively familiar with English terms I go by technical meaning rather than tradition.

But in this case it suffices to specify PI or power tubes.

Agree that grid leak is always the correct term. When we throw in 'feed' it usually means from a source external to the local circuit but can be a little vague, and maybe cause confusion. I also have used the term 'bias feed' when referring to the resistor between the bias winding and bias diode, so not the most precise term.
As you say, specifying the tube being discussed makes it clear.

Also grid (potential/voltage) reference resistor would always make sense, allowing to distinguish from the grid stopper.

Being as terminology can and does get mixed up. Often. And I don't even know what's "right" or "wrong" sometimes unless the common nomenclature is precisely accurate (ie: coupling cap) I'm usually able to reason what a poster means by taking questionable references in context.

I knew Pedro was writing about the power tube 'grid leak-bias feed-grid load-grid reference' resistors only because of the VALUE he mentioned. I know THAT value for THAT resistor to be a common difference between many BF and SF models.

I'm usually able to reason what a poster means by taking questionable references in context.

So do I.

But from the context assumed that Pedro was speaking about the PI circuit.
It made sense to me to call those resistors at the PI grids bias feed resistors as they do supply the grids with the bias voltage (more exactly: the bias reference voltage)..
Also there are a number of different SF versions and I have seen 330k used there, so even 220k or 100k seemed possible.

I have called those PI resistors "bias feed" before. And the discussion in the surrounding posts was discussing the PI. All is well that ends well.
