Default Re: Moreton Cheyney

I've been reading stuff on a guitar amp forum and it seems 2nd order distortion is common in cathode followers especially when anode and cathode resistors are selected to actually introduce this type of distortion.
As most of the resistors in this receiver are way too high that might explain what's happening so time for some experimenting. Looking at my V11.. this is a strong candidate but I'm thinking also about the purpose of V10 diodes...

It seems the mellowness of valve amplifiers can be because of 2nd order distortion.. but let's not go down that path. Leave it to the guitar enthusiasts...
