Please please please - vacuum tubes!!,,,
Come on, it's one of the most fun thing you can do with a circuit!
One of the most fun things? I was a practicing engineer for 5 years with a Masters in EE and I’ve never used tubes. That said, everyone wants them so I will re-double my efforts. :-)

Thank you Frank K, if this app gets support for Vacuum Tubes, I'll buy it! Analogue is all I work on.
A agree! Vacuum tubes are a must. I know it is only audiophiles and guitar amps, but that is a LOT of interest right now.
