Hello, We have an old HK model 6800 integrated amp that has a very intermittent runaway condition in one channels power amp. I have replaced outputs drivers, predrivers, etc. same problem persists. Sometimes takes 1 month to fail. At this point I would like to replace diodes in the amp section, but HK says NLA. Does anyone recognize the numbers 5632-10df2, and 5635-hz24-2L. I know the second number is a zener. Thanks in advance.
