Hello guys, been a while since my last post, all the usual s..t and also good things in life that takes you away from diying (regular job, on 6h shifts, and also got married)
yesterday I was messing with this triode tube, I tried the usual triode configuration and guess what, it works so good!!!
List of voltages and components
22n plate out
33k plate
22k grid
1M grid stop
1k cathode
10µ cathode
v in 11.9
multiplier 72.7
plate v 39.7
cathode v 1
mandatory values are the plate resistor and the cathode resistor, other components are up to you.
voltage is from 40106 multiplier, heaters are from a 7906 with a 4148 diode to ground on the middle pin (it goes 6.4 - 6.5 v so it's ok)
next step is a regular dual triode preamp...
