The rca shield ground connects to 1 end of a surface mount cap the other end connects to a resistor..


Is that resistor a 10K or does anyone know the value ?

Pm me I have the document if you need it...:)

I see 1k to the cap and then 10k after the cap

I just got the schematic from 1more amp.. But cant seem to find the part im looking for on the schematic..


The part is located on the bottom of the board not sure if its a diode or resistor but it connects to leg 1 of the D2012..



Its in the area marked 2 on the bottom of the board anyone know?

You need to include the circuit board designations for every part that you're referring to.

This is the part im refering to anyone know what it is and the value ?

It looks like D3 and it connects to Q1 which is a +15 volt rail pass regulator and the part number is 02DZ16F-Y Zener Diode ...:)

It appears to be D3. Likely a 16v zener diode from the part number (page 13 of the service manual).

Would that cuase the amp to draw excessive current?

Perry Babin 7th May 2012 03:03 AM

Many things could cause excessive current draw. Have you check the bias?

Have you checked the DC voltage (down to the millivolt) across the emitter resistors (limiter inline) to see if one channel had more current flowing through the outputs than the others?
