300B with 6H30 "diode" bias

Post by docali »

Hello Stephie,

corresponding to your suggestion I tested an 300B single ended amp with tube diode bias but to my surprise while simulating with Spice I loose a lot of gain/power which is comparable to an resistor bias without an bypass capacitor. My intention was that the dynamic resistance of the 6H30 would have been much smaller. Did I something wrong?

Best regards,
