Looking for DH500 schematic - original series
I have a DH500. Circa 1982
The right channels is now making nasty loud pops and shutting down. I seem to have lost the manual and the only ones I am able to find on the net are for the more recent version. Anyone know where I might find the older version of the manual? Recommendations for cap replacement are welcome. Cheers, Noctal |

I found the 1987 manual...
Here's the link...It might be too different from the earlier one to be useful though...I really don't know...

The only real difference is the DC balance control.
You should be able to fix the amplifier with that data. The PC6 board is probably what you have: http://www.hafler.com/techsupport/pd...00_amp_man.pdf
