For the sake of understanding I wanted to keep the numbers simple there Doc..

Did you look at the Valvecaster pdf..???

Yep, had a look at it and it looks like it's not that hard to build at all, I seem to remember building it a couple of years or so ago.


The way Matsumin, the designer of the valvecaster circuit, goes about implementing a gain control is a bit unusual, I had to mod my valvecaster build so that the gain control worked a bit better cause when it was built as per the circuit diagram it sounded a bit mis-biased, or it could have been due to the valve I was using at the time, I'll have another go at building the valvecaster circuit and will make sure I start a build-thread for it, will also do some signal tracing with a signal-generator and scope (will post some screen shots too) once I've got it working properly.

Most of us drive cars and listen to music and go through life never knowing how the internal combustion motor works or what a planetary gear does or what intonation is or the fact that there is something called a 12AX7.... yet it doesn't stop the human race from enjoying those well written good music in our beautiful and fast cars...

Use what you do know and make the whole world a better place for it...

An excellent sentiment
