no, I wanted to check because one side heats up more than the other, but the sound is good...Service Manual is in german

unfortunately I do not understand the procedure because the service manual is in German and I do not have an injector signal 1kHz
Tnx Ok tomorrow i check this but i don't understand how to proceed.
volume to zero? speakers connected? I tried with an ocr program to translate but
Don't work on PDF.
Find the posts on adjusting the PMA-520, which also has an optically controlled bias. I was never comfortable with the procedure, it behaved quite strangely when following it, but sounds fine.
thanks finally in perfect English. Now compare the tensions. I do not understand how to measure one side and within 10 seconds of each other? I have to use two voltmeters or as a means for marantz measures taken in parallel? or do a first channel and then the other by turning off the amplifier to cool?

done all the correct procedure here.
all the trimmer counterclockwise to zero, no speaker connected to all switches off. measure the voltage on tp and take it to 8 mv. 10 minutes go check that it is still sent to 8. So send 1khz and raised approximately at 9 o'clock the master volume up to about 11mV read you will see that at a certain level back to 8mV. stay in between max and min and then act on other trimmer and bring to 30mV. thanks to all
