Changing Pultecs Frequencies

[echoplex]

Hi there,

I've bought a pair of used AML ez-EQP1 Pultec clones and I wonder how difficult it would be to change the fixed frequency points or even extend them by additionals.
Is it just changing capacitors? But then I again I'm afraid it's not that trival and way more complex than simply exchanging some capacitors. Has anyone done Pultec mods like this before? And how complex is it and where can I read into that topic?

thank you

I'm pretty sure we've discussed it before - have you looked in the relevant help thread?

in short it's just about the series resonance of inductor/capacitor. No rocket science. Don't believe anybody claiming  esoteric origin of the original.
