Firstly I must appologise for writing in English!! :lol:
I have a PM55 amp. Which I have just got out of storage to try to fix. It sometimes works then makes clicking noise through speakers. Then fuses.And sometimes will not work again for a few days!! I have read this is someting to do with the relays that chorode.
I am a novice with electronics so please be easy with me :lol: How do I identify the relays to clean up. Or do you guys perhaps have another solution.
Big thanks in advance!!! Lee
Welcome mingualez,
Do you live in the Netherlands?
If you do so, then you can contact our friend and master fixer HAL9000!
He knows a lot about Marantz and he fixed mine 2226B very well!
Sadly no!! I'm trying to fix myself as the service cost out ways the value!! Thanks for your time.
I'm in the UK.
stupid
Open up youre amp put it on power , and then switch the selector ( DON'T TOUCH ANYTHING WHEN OPEN) , usualy you can see the relays working ( were the clicking noise is coming from)
Sorry for my poor english , its better for me to speak youre lanquage
grtz Mars
edit ; i mean , don't touch anything inside when the amp is open

Hi there,
You need to replace the hybrid integrated circuit. STK-xxxx
Look for bad solder spots and burned components.
Also replace all the ELNA capacitors.
These amplifiers really sounds nice! i have a Pm64 (15 years now).

Ok it's been a long time :yes: Been using different amp. But really want to get this one fixed. Having trouble identifying relay to clean corrosion off. Tried to upload a pic, can browse and find file but cannot upload to post. I am struggling to translate forum. Not sure you can see??
Thanks for help in advance :-)
