i noticed there was 4 different secondary part #'s linked to the part # you gave me

Exbass17 · 4th March 2013, 01:09 AM

ok thanks Perry will do and beings i swapped a part i was unsure about i went with my power supply and a smaller speaker to be on the safe side

Exbass17 · 4th March 2013, 01:10 AM

so power the amp and check the voltages on the Outputs your saying?

Perry Babin · 4th March 2013, 01:36 AM

The various parts have various levels of distortion. You can use the cheapest one.

Output pins of the op-amps, not the output transistors.

Exbass17 · 4th March 2013, 01:41 AM

would the expsensive one have a better distortion rate then and could i use that one?

Exbass17 · 4th March 2013, 01:45 AM

i dont have a amp meter if that is what your asking me to test

Perry Babin · 4th March 2013, 01:53 AM

No. I need you to measure the DC voltage on the output pins of all of the 8-pin op-amps in the amplifier. The output pins are 1 and 7. Pin 1 is near the white do on the board.

ok ill check all the voltages of all the 8 pin op amps 1-7 and give you some readings also will it make any difference between using my power supply for readings vs my car battery

Please don't post in a repair thread that was started by someone else unless you are trying to help them.

Contact MTX. They will give you the resistor values.
