Maxamillion, what does the choke to ground do in lieu of a resistor in your amp?
I don't need grid current so I chose the CCS, I will say this has been one of my favorite tubes so far for my amp. It drives the 300B really nice with no coloration. Just got to figure out what's going on when I turn on the amp with a signal.
I might try your diode bias scheme next, might correct my little issue.
Follow Ups:
That's a Lundahl grid choke. Just a substitute for the typical grid resistor. It gives a low impedance for DC (5K) together with a very high impedance for the music signal. It's not critical to the operation of the circuit, I just thought it would be a nice enhancement vs a resistor.
Never thought about putting one at the input tube.
I have a couple magnequest bcp16 nickel chokes lying around I might try.
