Hafler Amplifier Repairs
Hafler DH-200
This was working okay but needed the quiescent setting for the two channels, I also put a relay in to switch the mains instead of the actual mains on\off switch to save the contacts from the sw-on surge as it's a bit fragile, the speaker fuse holders were changed to an original type as there was one 20 mm and one 1.25 in fitted?, a great sounding amp with 4 MOS-FET's as the o\ps, and very similar to the Sumo Polaris I had.
