Eldartford's comment about rebuilding an old Dynaco amp reminded me of an advantenture during my undergrad days, about 50 years ago. I'd successfully graduated from Heathkit to Dynaco amps, so a friend asked, and I promised, to build a Dynaco preamp by Christmas. What a foolish promise! The simple amp turned out well, of course, but the preamp was a disaster. Thus endth my kit building.
