Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

Interesting ...

Hi Mark, your input is much appreciated; it's great when something makes sense.

Pico actually provides a THD figure but more often than not it appeared to be too low. I assumed some cancellation of the harmonics must be at play but perhaps not.

Interestingly it was much closer on the 845 amp, which happened to have lower OP distortion. Figures for the 845 amp were Drive o.11THD and Spkr 0.41THD for example one and 0.035THD and 0.55THD for the second.

However, for the 300B they were Drive 2.78THD, Spkr 0.61THD and Drive 2.1THD and Spkr 1.18THD respectively.

Can you offer a possible explanation?

Thanks,
Naz
