Hafler PRO-5000 schematic

[steelguy]

Anyone have schematic for Hafler PRO-5000 stereo amp? I have one with one channel out.

It's usually a blown resistor, that ties the driver circuit to ground.
Poke around with an ohm meter and usually it's find-able.
This resistor blows to protect the amp if the output is overloaded. Replacing it will many times make the amp work again.
OR, it "could be" something else blown, but check that above first.

The Hafler web site has several Pro series amps as well as some other P series amps covered under tech support, library archive. No 5000, but you may find other models close enough.

PRO2400 sch, may be close enough to do fault finding with.....
