All measurements were done with the output in a 12 Ohm dummy, using a PC + soundcard.
Frequency response:
Harmonic Distortion @ 1/4W
Harmonic Distortion @ 1W
Harmonic Distortion @ 4W
Almost all debis comes from the AC filament supply. This is something I'd like to work on in the future. The lower harmonics are quite constant with 2nd @ -78dB rel and 3rd at -70db rel. The higher harmonics increase with power.
