Home Forums Design and Building Tube Talk Best Tubes for 2 Stroke Re: Re: Best Tubes for 2 Stroke


I’ve post a schematic of the solid state circuit and switch in my “2Stroke” photo album. As I mentioned in the first post, a modern 5Y3 will not have much voltage drop from the SS circuit (probably what you notice between your Weber Copper cap and the Sovtek tube) but a NOS 5y3 will have a much larger drop and give you a larger tonal difference.
The circuit is really simple to build, in fact you could build it right on the back of the rectifier tube socket, using the unused lugs as terminals for the diodes. I used 4 1N4007 diodes.
