Default Re: making an audio output triode...

A few guitar amps do use triode power valves, and that's why I'm interested in seeing the clipping wave forms. This could be very useful for a small size, low power guitar amp, or for driving a spring-reverb tank. I'd also like to try making a small HiFi amp using this mehtod, for a Laptop for example.

Your English is ok so far!
Hi Merlin,
what is a spring-reverb tank?
If the thing sounds good, I'll make selected transistors for the triode multipler and high quality output transofrmers available.
