With a little screwdriver.

OK, the default values are midway, and you can tweak the values
to taste.

Screwdriver + carbon pot = Hi-Fi cocktail

I used in the curves seen in "Feastrex Fun"
Great!!

Ok, I see that 25 K pots are for frequency adjustment, while the 10 K one looks like a notch filter...
When the buffer article gets published, it should be fun to play with its implementation...
Thanks! 🙂 😎

What would you call this, semi-active, quasi-passive?
If it works anything remotely like the way I suspect, you'll see it as an active circuit.

In case you do not go wandering over to the Solid State forum,
I have posted some circuits and results in the Lightspeed Attenuator
thread, starting with post # 1327.

Nice goodies.

Thanks Nelson.
I couldn't imagine a simpler buffer. I guess that it requires a rather quiet power supply. It seems that two 9v batteries would work, while 7815 and 7915 Ic regulators may be noisy for the application?

That's a CURL buffer, by the way.

Q for Papa - compromises ?
Papa - do you mind writing few sentences - about compromises STILL present in PL products ?
it's not necessary to mention all exact ones, I'm just interested in your overall approach to them ;
as you can see - I'm not bugging ya for another one schematic ( and then another one and then another one and then another one ......)

Re: Q for Papa - compromises ?
As you should well know, there are no compromises in PL
products.
