I've been looking over documentation I've assembled on the Sherwood audio stage modification.? I have diagrams from the April 1979 HR article, from MODS.dk and from the files section here.? Since none of these except for the HR article are dated, I'm unsure which is the latest improvement.? Hopefully someone can point me in the right direction.? Apparently after the HR article, there were changes made as follows but I couldn't find an explanation for the changes: 1. The .22 cap and 1500 resistor on the input were eliminated, 2. The 200 uF cap on pin 2 was changed to 400 uF, the 390 ohm resistor was changed to 270 ohms.? Which version of the circuit is the best one to use?
