Carl Gigun | Re: understanding voltage feedback in common MI amps That a cool explanation, Speed. I never knew about the jtm45 having the most nfb, interesting bit of history. I installed a variable nfb in my amp using the jtm45 47k series resistor and a 5k pot wired as a variable resistor, no presence control. Very noticable changes as you turn the dial, except nowadays I pretty much leave it cranked to the "no feedback" end of the dial and use ultra linear mode to get the bass under control instead. -Carl Gigun |
