Vacuum Triode Amplifier (Floyd Sweet's)

Recommended Posts



I am interested in replicating Floyd Sweet's Vacuum Triode Amplifier. I have found two web pages that describe the respective web page owner's method of constructing a replica of Floyd Sweet's Vacuum Triode Amplifier. The web pages are http://www.hyiq.org/Library/Floyd_Sweet-Archive.html and http://jnaudin.free.fr/vta/vtabuild/index.htm It seems to me that these two web pages describe a different design of the Vacuum Triode Amplifier. Does anyone have any experience replicating Floyd Sweet's Vacuum Triode Amplifier. I would appreciate any advice.


I am investigating what type of wire I need to buy. However, it seems that the hyiq.org web page design has two coils that are not wrapped around the magnet and there are two magnets; where as in the jnaudin.free.fr/vta/vtabuild/index.htm page three coils are wrapped around the magnet along different axis.
