I did as you said and now get 8.13k and 7.30k. Still way out of either spec. I don't quite know how reliable the schematic is since it's labeled as being for an earlier serial # series, so I can't even do the math to determine the resistance I need. Who knows, the final output voltages on the schematic might be different than what my model needs.
McIntosh is sending a copy of the manual via UPS. If this doesn't have what I need, I'm going to have to forget the schematic and replace them with 12k as used in the circuit.
For the second part, what you're saying is that I should test a component in and out of the circuit and, if it falls in spec out of the circuit, use the in-circuit value to test other same-resistance components. Correct?

You should probably de-solder the components for accurate results; at least one contact anyway. You could be measuring lesser/greater resistance/capacitance while the part is still in circuit. When you find a component that is still within it's tolerance spec, you can use it temporarily to take readings from the various sections that use the same values. That way you'll know which sections are good or bad according to the manual. What I am getting at is, you don't want your readings skewed due to faulty components from the get go. Do you follow me? ~Zip |
