RE: how to remove feedback loops




I drew this up for you vinny... try it on your breadboard if you like.

lm334 ccs uses 20 ohm rset to ground. negative supply is optional but not needed.

you could use a trimmer instead of 20 ohm resistor... 10 ohms is 10ma I think, 68 ohms is 1mA.

should be class A operating point. 12at7 driver as ran differential pair/LTP.

I've done it with 12at7, 12au7, 12ax7. very simple circuit.
