Please Guys!
Can somebody could help to understood those Jim Williams recipes?
I'm on the way to finish my NT2, and i really want to apply those mods.
I wrote to Jim Williams on his mail, but he didn't answer.
If someone have any ideas, i'll be thankfull for help!
Schematic (jpg) is on attachement.
"First, the inductors off the output leads need to have a series resistor installed, I use 56.2 ohms."
Do i think correct, that Jim put two 56.2R resistors in series, one between L1 and xlr pin and second - between L2 and next xlr pin?
"Then the capsule polarization voltage is set too high. It needs to come down to +60 volts. To do that, I install a series resisor (1.5K) from the + V line feeding the oscillator pcb. Then a zener diode is fitted to clamp that voltage down until +60 volts is reached. Anything from 6.2 to 8.5V zeners will get there, select imperically."
Do i need to put 1.5k resistor instead "white wire" (from schematic) on +V point?
And here's the worst part:
"Then a zener diode is fitted to clamp" - where, what clamp? Where i need to put zener diode? Or He mean a zener D3 from schematic?
