Pretty clean, Romy (and one hellova tranny at Fundamentals)!

I thought you said Vishay metal foils in your earlier response about bias adjustment? If so does that mean steps, or...  how, exactly?

The Vishay metal foils are not stepped attenuators but regular trimmers. At this point I decided do not go for them and to use regular Bourns cerment trimmers.

When you specify "Full" or "1/2" at LF, MLF and injection speaker level do you mean another cap in series that is either a repeat or 1/2 of the cap value that is called, for the lower total capacitance?

Nope, I meant a full 6C33C vs. the 6C33C with one anode.

Also, will these caps in series straddle the hot end of a resistor or variable resistance run across the poles in your "active" arrangement? I still aim to try it myself, on your recommendation, but I have to admit I do not understand how this works, and I ass-u-me that you still have to "increase" the value of each of the two caps in series to arrive at the desired working value, resistor notwithstanding?

I’m sorry I do not understand it….

Pushing my luck, are you trimming gain to the ribbon at line level with only simple resistance/shunt?

It is not a shunt. The high-pass filter woks ageists this attenuator and therefore it could not be a shunt. I use a laden-type 24 step with “fixed” input impedance.

Does Alex's attenuator figure in to this?

I do not know what it mean…

Going for gold, where does EQ happen at injection channel?
