i've been digging into my recently-purchased Quad ( a 1E model w/ dates of July 1990 on the reverb spring, ser # Q2031). While tracing down and LDR problem on the LD2 channel (low volume for several minutes when first activated), I've found that the schemo I've been using (listed here C:\Amp schematics\Mesa Boogie Quad Preamp Electronic Circuit Schematic_php.mht ) is less than accurate. For example, it doesn't have all the LDRs, and the pull deep switches are missing. I've checked several sites and this is the only schemo I can find.
Does anyone have a quality Quad schematic?
