WebDec 2, 2010 · As I understand it, basically, a gyrator allows you to set plate voltage while the tube finds its own current, while a CCS allows you to set current while the tube finds it's voltage. I'd think the gyrator might be advantageous for DC coupling because of that. The shunt should scale, providing you can find parts that can handle the voltage. WebDec 6, 2016 · 75V 2 / (8 * 4200) = 167mW. In contrast, a 3V ptp signal (about 1Vrms) is the largest the amp will want before the grid goes positive. Again using the plate curves and loadline, this looks like about 110V ptp, or 360mW. The amp would not be able to do that without adding some (possibly significant) distortion.

WebIf the parafeed coupling capacitor is correctly chosen, and if the speaker impedance is nearly resistive near the low frequency cutoff, the tube can be made to see a nearly resistive load to a lower frequency that one would calculate from the inductances alone. This smaller phase shift reduces tube-generated low frequency distortion., giving a ...

If you've got conventinal parafeed amplfiers, consider the Ultrapth connection as opposed to the usual capacitor-to-ground connection of the OPT. Then possibly experiment both with and without the cathode bypass capacitor. If you've never done that, I encourage you to just give it a shot.

WebMar 23, 2012 · Parallel feed (parafeed for short) changes this topology a bit. Instead of running the DC through the transformer, you instead use a different load for the tube (a choke, a resistor, or a constant current source (CCS)) and capacitor couple the transformer to …
