I'd previously built a Millett Hybrid solely out of parts I had laying around in my supplies, and to go with it I built a discrete diamond buffer, again only out of my normal supplies. I didn't have any surface mount resistors for it though, so I had a bit of fun putting through hole resistors on the board. Just something I randomly decided to do last night while I couldn't sleep...
I've looked and I haven't found anything good around here I can re-use as an enclosure for the MH (to keep with the $0 cost so far), so I'll probably just mount the amp on a piece of wood or something.
