Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

RE: confused again

It will be a lot less confusing if you have a coupling cap. The grid of the output tube will be at 0V DC, then you can bias up the cathode accordingly.

Direct coupling means that you are relying on the plate voltage of the driver stage to be predictable so that the output stage operates properly. This isn't always the easiest thing to do. You're also going to run the same output tube current through a much higher value biasing resistor, so heat will become quite an issue.

You also don't seem to have enough B+ to properly run a directly coupled circuit, at least with what you've been discussing.
