Hi,

My future project is to build a Mangler cause i recently have 2 Nkt 275 with hfe Q1 : 120 and q2 hfe : 80, do i have to change the trim with for a 10k with 3k resistor ?



thank you so much

Per the build doc use a 20k trim pot to bias the transistor ( around -4.5v).

If you want to use a fixed resistor, measure the trim pot R after you bias and replace with an equivelent resistor value.

However, you will allow yourself more tweakability if you just the trim pot in there.
