1953 Geloso G211a - 3. Grid leak bias, negative feedback and power bias trouble

This episode was intended to contain some nice experiments with sound clips illustrating the differences before and after mods. After not too long I learned I shouldn't mess with the input capacitor, this is stock and staple 50s electronics. The experiments with biasing the amp differently completely went up in smoke as the bias pot burnt out because I wired it wrong... After completely re-doing that part, there was still some time left for playing with the negative feedback loop, which I decided to remove all together.
