The tranformer is the only significant thing I did (of course, with the obsession common to all of us, I should add SO FAR). I may have also jacked up the bias a little bit.Not to continue assaulting your memory, but I believe Erno Borbely generally gets credit for designing the DH-200. The only changes in the 220 were mechanical (the input jacks were changed to side-by-side; the 200 had the left on the extreme left and right on the extreme right), some parts upgrades (carbon film resistors to metal film in some spots, better caps in some places) and a slight difference in the input circuit. This resulted in a new circuit board (the 220 and the 500 both used the same board).
There was a 2 part interview with David Hafler in Vacuum Tube Valley about two years ago focused entirely on his career through the Dynaco years.
