I don't have many pictures, mostly because I've only done this to my DH-220, and the job is easy. As a matter of fact, I only have one picture to share. It's of the bridging switch and also shows the input jacks that I've replaced. Actually, in this pictuire they're still in limbo. Now they're gold RCA chassis mount connectors. Normally, that would be a problem, because Hafler made the mounting holes the same diameter as the barrel of an RCA jack. Well, I went down to the hardware store and paid fifty cents for the fix. I got a pair of nylon shoulder washers (.37 inch O.D. sleeve, .25 inch I.D.) and two ¹/₄" brass washers. The majority of the sleeve of the washer was removed with a hot knife. The nylon washers go on the outside, and the brass washers go on the inside. Apply your RCAs to the (now properly bushed) holes and wire 'em up. Don't forget to reinstall the chassis ground to the input grounds.

Enough about my adventure in the changing of the RCA jacks. Here are the links to bridge your own amp:
