Default Re: making an audio output triode...

Hi Merlin,
a transistor and a pentode do have the same output characteristics.
And there are a lot of nice pentodes available, so this makes no sense to me.
If you connect the plate of the driving triode to a fixt positive voltage the arrangement has the same characteristics at input and output like a pentode.
I want to have a (power) triode.
