Hi,

I have a Pm655 HK integrated amplifier and if appears to have some problems. One of the channels appears to be shot - i.e very low volume with lots of distorion. Any thoughts?

Also, I'm looking for a schemtic for this amplifer so that I can test some of the components.

Any help would be appreicted., John

you can download the complete service manual for this model[7.26 mb PDF file] direct from HK here...

[url]http://manuals.harman.com/hk/Service Manual/pm655 sm.pdf[url]

i haven't downloaded and checked to be 100% sure this is the right deal but they usually are..harmon kardon has manuals for just about everything online....you just have to guess and hit the right filename as they're "hidden" with no directory listings..anyone else looking for a HK service manual can try the same link above but just change the model number to the one you're looking for.

note:you may have to experiment with adding/removing spaces etc to get the right file name...

Hi John,

I know your post is a few years old but I was wondering if you had any luck with your amp. I have a PM655 with the same problem.

Hi I had the same issue and found that a really good cleaning including using lots of de-oxit on all the controls inside brought it back to life. I read that this amp is higher maintenance for cleaning than is normal.
