So I'm working on a 45 SET and I was wondering if this is a normal level of harmonic distortion. This is one watt. The test setup is the a signal generator into the amp driving the 8 ohm dummy load on my Sencore PA81 amp analyzer. The scope out signal goes into my soundcard for the TrueRTA software. This isn't calibrated but it should give some approximation of the spectrum.

At 1/8 watt the second harmonic is down to -39db relative to 0dBu. 1/8 watt is all my amp will put out with my current gain structure. This will drive my Khorns to my normal level of around 80db average at the chair.
