What are the trade offs? PUSH PULL vs. pure SET
Thanks Atmasphere it is always a compromise look at this link from Steve Vaughn's Home page link best to you Groovey Listening to Simon & Garfunkel-Bridge Over Troubled Waters- the Only Boy Alive in NYC |
Hi Groovey, thanks for the link. In general Eddy is on the money. He does leave out some details that *I* think are important- namely OTL amplifiers. Take away the output transformer and you remove most of the arguments for SE. So it then becomes possible to have more of the best of both worlds- low harmonic generation along with power and bandwidth. Negative feedback remains optional (in my case I disdain it as it robs the music of soundstage depth and adds and undesirable 'sheen' on top). All the Best! |
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 Groovey Records Listening to- Charlie Mingus-Blues & Roots-Atlantic SD 1305 |
