Yeah, my input impedance for the amp I use is around 80K @ 30Khz. I'd say the output impedance for the preamp is around 1K. Certainly higher than the "standard" 600ohms but quite adequate for coupling to my amp. So yes, I just use a coupling cap to the output (1uF Solen/Angela fast cap). In that discussion about oscillation, I mentioned that I was already using a grid resistor. My plate resistance is 6K and my grid resistor is 6.2K. I haven't tried shorting out the grid resistor to check for oscillations yet.Tom §.
