Hi,
My trusty amplifier has burnt one resistor (my fault because I reconnected some wires in the wrong position). I have photo of the board before, but the quality is bad and I cannot be sure of what type of resistor it is - the colors are not clear in the picture.
I would love to have the service manual for this amplifier. Can anyone e-mail it to me? My e-mail is joaquimfonseca@netcabo.pt
If this resistor has burnt what are the chances that other parts have also suffered? What else should I check? I guess that the cables that I reconnected on the wrong position are one of the 2 in the pictures.
Thanks,
Joaquim

Thanks
Obrigado! 🙂
I thought that with the service manual I would be able to figure it out, but guess what... I can't! 🙁
So I need some help here.
1- What type of resistor it is? What are the colors on int?
2- Do I need to buy a specific brand or any brand will do it? I would like to avoid to buy cheap components that would ruin the sound quality.
3- I need someone to tell me exactly how those 2 cables should be connected.
4- I need someone to tell me what else might have burnt
This is very old, but the sound is very good. If I send it for repair here in Belgium I think I would pay a fortune, so the only option is to try to fix it my self.
I know how to solder, deolder and most of the basics. But I cannot do such a repair without almost a step by step help.
Thanks

Use the 'search' feature in this forum and search for 'PM66' and you'll find the solution - it's R802.
In your machine, R802 (& R804) have already been replaced.
If you've connected the above cable incorrectly, you may have destroyed the RIAA equaliser - you'll need to fix the power issue first. Q801 may also be destroyed - it's severely stressed (it desolders itself due to excessive power dissipation) in the default configuration.
Good Luck!
Hi jfonseca,
Hope you are safe.
If you have the Marantz PM66 Manual could you email it to me at teverygo@gmail.com
