Thanks Jazbo8.

Im getting mixed messages about the first circuit from several members?? Im not a techie so I rely on others to guide me. Could someone please give me a straight answer if the first circuit is a no go or not. The circuit designer seems to be an experienced designer and has test results to show that it in fact works.

Thankful for any input, cheers.
It's a no go, the second triode stage cathode has no dc connection with ground. It won't work.
