HK PM660 - What do with amp sections?

Can I bridge two HK PM660s? Or use them as monoblocks?

Hi All-

I have two Harmon Kardon PM660s with bad tone board sections. They seem to both work fine with the 'main direct' switch which bypasses the boards. I've tried to troubleshoot the boards but it's beyond my ability, and my focus now is building an Aleph J so less interested in spending much more time on it.



So, with the two amp sections could I bridge them or use them as monoblocks? I would need to do more research but not sure how that works. I could also use the amp section to make a 660 power amp.



Basically looking for something interesting to try and a fun project. Or just try to sell them as-is and put the money towards AJ.
