John, When you had these experiences, were you running two tubes in push pull or parallel? Just curious.. Rick/K5IZ John Coleman ARS WA5BXO wrote: I do not have a ranger or have I had a ranger, but I just can't see how replacing a class C tube will change the power. As far as I know

[AMRadio] Class C final tube swaping

I do not have a ranger or have I had a ranger, but I just can't see how replacing a class C tube will change the power. As far as I know the ranger is a class C output and not a linear amplifier. To me a class C circuit is a switch which gains its efficiency from the fact that it doesn't s
