I've also found Manley customer service to be outstanding.
FYI Chinook Owners -- Diode Failures and Repair Upgrade
Hey There Manley Chinook Owners!
My Chinook stopped producing sound a few weeks ago. All tubes checked out fine as well as connections. I checked on things and everything looked great. I was stumped.
I placed a customer service ticket with Manley. Well, the lovely EveAnna Manley contacted me herself! Wonderful person and a great business owner in this hobby--in my humble opinion.
At any rate, Ms. Manley informed me that several diodes (On the power supply board, D9, D10, D11, D12) need to be replaced with some Micro Commercial Components (MCC) Schottky 5A Barrier Diodes Part# SR5200-TP. I think the previous values were lower amperage and now Manley specifies 5A.
My unit is out of warranty so I told EveAnna that I'm decent with a soldering iron so I'd give it a go myself. She said if it doesn't work her guys could fix it. EveAnna was super gracious and offered to send a tech bulletin and the schematic to make my surgery easier.
By the way, (and I'm paraphrasing here), I think EveAnna mentioned that not everyone will have this issue. It does, however, occur over time. I thought it might be helpful for other owners to know this as--if you're like me--it's easy to get frustrated when such a great piece of gear quits and I cannot easily diagnose the issue.
