Proceed AMP5 in protective mode

Sounds like Dbtrucks and I are in the same boat. I would appreciate hearing from you when you have more information.
I have emailed Harman Special Products support to see if they have any information to offer.
Maybe somone else can repair the unit at a lower cost. I also do not feel like spending 800 dollars for a discountinued product that is worth 1800 dollars. Plus of course shipping which wont be cheap at 110 lbs

I talked with David Schulte on repairing these amps and adding the upgrades to them and he said he was no longer interested in doing the work after I sent mine to him. He told me that the Nuforce 9 amps are superior to any amp he has heard including upgraded amps he has worked on. If I decide to have him fix my hpa-3 I will ask him what parts he replaced and share it with you. If anyone knows the fix I am all ears! I just went on-line and saw the pictures and specs of the Nuforce amps. The nuforce 9 is only 7lbs.
I can tell you one thing, David has never steered me in the wrong direction. I am going to seriously consider the Nuforce amps.

Is your amp less than 5 years old? Harman Specialty Group honors Proceed warranties, at least that has been my recent experience with my AVP-2.

This is a follow up with a great ending .

After taking the amp to my local Levinson dealer , the tech pulled the control board and reinstalled . The problem was found to be a cold solder connection .

It's been home a month now and working 100%

I tried Dbtrucks solution and it didn't work. I had to send the amp back to Harmon Special Products. They reaired it for $800 plus shipping. The rpair description was really cryptic but it appears they had to replace several components on all 5 channesl and some of those components were resistors. Other parts were simply described by part numbers.
