NAD 7240PE - Need Resistor Values
Hello,
I am currently working on a couple of NAD 7240PE receivers. On one of them, the soft-clip feature is not functioning properly (enabling it causes the right channel to clip at a low level). The problem seems to be four cracked resistors at the back of the unit, near the soft-clip switch. They are labeled R413, R423, R414, and R424. I need the values for these four parts. On the unit where this feature works OK, all four of the resistors are 1/2 W 10 kOhm with 1% precision. The bad resistors are 1/4W 8.2 kOhm with 5% precision. Unfortunately, it appears that all of these are replacements; I don't have the original parts. I could use 1/2W 10k's in the bad unit, since they seem to work in the other one, but I'd rather be certain of having the optimal values [especially since I am planning to sell the amp after fixing it]. I know that some of you have the service manual. If you could provide the original values, I would appreciate it _very much_. Thanks :-) Matthew Varney |
