What are the trade offs? PUSH PULL vs. pure SET


Is the triode circuit of a push pull design compromised because of its ability to go to Pentode/Tetrode? Is the triode circuit in a push-pull even considered to be single ended. ?

If not what differentiates the design from pure SET?

Thank you

Hi Atma-Sphere
After you responded to my thread your moniker rang a bell and i remembered hearing about your designs elsewhere (Arthur Salvatore's woofer in sheeps clothing) so I looked in on your site and read alittle here and there.

I am still at the research stage and will leave my final decision a while longer.

When I asked Arthur specificly about OTL he said "Everything being equal, I still prefer SET amps or amps using DHT output tubes, but a good OTL amp can be an excellent choice depending on the speakers."

In that context my room is very large with a cathedral pine ceiling walls and floors. I have 89db 8ohm JBL 240 Ti that I enjoy very much. They are a full frequency speaker, not as low as a sub but claim 37hz- 27k. For now they are my systems strength not its weakness.

As for the present thread where does DHT output tubes fit into the big picture
Are they a design option for SET alone or are they more VERSITILE fitting into PP, SET,and OTL design parameters ?

I only have enough knowledge to be dangerous so please share what you can.
thanks

Best Regards
