Fixed Bias for a Single Ended Design?

[BJosephs]

I've built a couple of fixed bias 50 and 100 watt amps in the past. Messing with my valve JR and Blackheart amps has gotten me thinking about how Single Ended circuits work. My question is: Is it is possible to bias a SE output with a negative voltage (delivered by a resistive divider) and tie the cathode straight to ground? It sound like it may be an easier way to bias than trying different cathode resistors.

Any Thoughts? If I may try it and report back but I was wondering if anyone has examined this before.

Of course it is. The power tube has no way of knowing whether there is another powr tube or not to make it push pull. All the powr tube does is amplify what shows up on its grid.

A single ended bias circuit is exactly the same as a push pull but with only one grid to serve.

I have a cathode/fixed switch on my Champ...I prefer to keep it switchable, both methods have their merits.

And that is why when we converted a PV Classic 30 over to cathode bias we left it switchable as well.
