This brings up another question from me (you knew it would :razz: ). I thought tube grids were, in general, pretty high impedance. Why do I see resistors across the secondary of many line inputs? For example, on an LA-2 you've got a 68k. If the transformer were 1:1, which I don't know but just as an example, wouldn't that make the input imedance 68k? Why bother with that and just run the input straight to the grid when the impedance would be R6 (68K) plus the grid impedance making a nice high impedance load? I'm missing something here :?
