Marantz PM7200 Protection Repair Kit & Power Panel Upgrade .
(Amp fails, goes into protection mode or does not switch on.)
A PM7200 can go into protection after switching on either due to faulty capacitors or a faulty processor. The only way to determine where the fault lies is too use a multi meter. However it turns out %90 of the time it is the capacitors that are fault. The fault could lie in the protection circuit of the power board. I supply capacitors for both boards. Even if your amp is in good working order,it is worth doing this upgrade too prevent future failure.
It turns out Marantz used 85oc capacitors which where prone to early failure instead of the higher rated 105 oc.
The parts supplied are high quality capacitors with a life expectancy of around 5000 hours or more. They also have a higher temperature value of 105oc than the original 85oc ones.
(Full instructions with detailed pictures will be supplied with the kit.)
My kits come with detailed instructions & pictures which are easy too follow. No knowledge of schematics is required.
Even if you can't read schematics,you should be able too perform this fix.
(To perform this fix you need to be somewhat comfortable with a soldering iron, and be willing to take your amp apart. If you aren’t very good with an iron,then i can Cary the repair out for you. Contact me for info.)
