The following is for use in an experiment. I am not looking for audiophile quality.
I need to produce an audio frequency signal at 200Vpp 10W. Input is from a computer soundcard and function generator software.
Rather than use a step-up transformer or high voltage transistor, I prefer a single ended valve power stage. This is partly due to impedance considerations.
I am not familliar enough with tubes to design my own. Can anyone point me to a suitable circuit, or related information, that uses a single tube and HV supply?
Thank you,
Richard
