I am planing my 5E5 build and decided to use the unusual input stage (1 double triode for each channel, no grid stoppers, shared cathode resistor for all inputs). Heres the schematic: I am trying to get my head around this, because it seems quite different from the usual Fender input stage and I found no real coverage of this input circuit... My questions: 1) Am i right that the input impedance of input 2 of each channel is the two 1M resistors in series? This would mean that wehave 2M Ohm impedance for input 2 and 1 M for input 1 of each channel. 2) Since there are no grid stoppers present, am I right that the impedance is the only difference between input 1 and 2 of each channel? 3) if i plug into either input one channel, does some signal also pass through the second 1M grid leak/impedance resistor into the grid of the other triode? Heres the more common 5E5-A input stage for comparison: Thanks!
