"In multistage circuit, the last valve is the one that controls the output power of an amplifier. For it to conduct a lot of power, its grid voltage has to be swung over a very wide range. In order to achieve that range, the previous stages are used."Ok...so would I be correct in saying: The higher B+ is (greater Voltage), the higher the modulating voltage MUST be on the grid?
If this is the case, then it would seem that it would be VERY near impossible to have a line level input modulating a SINGLE high(er) power amp (no in between stages)...you kinda have build up the modulated signal until it's big enuf to actually properly 'feed' the main power amp tube.
Groovy...I think I'm finally getting this!
