potentiometer adjustable cold clipping?

[pjd3]

Just curious if anyone has tried an adjustable cold clipper cathode resistance using a potentiometer.

Looking from a distance at the voltage and current expectations down there, is there any apparent reason that it would be problematic?

Thanks,

Just a little noise when you adjust it.

You might want to have a resistor in series with the pot to make sure there is a minimum amount of resistance between the cathode and ground.

That's good to hear, thanks for the tip.

I bet that is why you only see variable cathode resistor in the form of a switch, like the Structure switch.

And sure, a minimum value resistor. Maybe something like a 1.5K in series with a 25K Pot. May have to try that one day,.

Thank you!

Best,

I use it as a tail on a favored R/C.

You will be happy with many choices. I use 25k pot on center biased limiting or higher R.

Feel free to fully bypass adjustable stage.

disregard, read cathode not clipper. DOH

But T, I can't disregard.

I must clip with my cathode....,,.Kiddin.

LOL, yeah I wrote like 2 paragraphs about an adjustable cathode "Fat circuit" then looked up and saw cold clipping on the title
Guess my coffee hadn't kicked in yet
Carry on!

Well ya know what T ?

Your efforts shall not be in vein. I would surely be interested in what your severely maligned thesis on that would be anyways.

Might be an inspiration for another kind of mod one day.

Thanks,

Old post, I know... but I am working with a cold clipper on a Bogen conversion and liking 10k a lot at V3b. This is 110 Bogen. So I am curious if you have implemented the pot idea? 27k was blah but it seems that between 6k and 15k there is a lot of useful territory.
