Jim, I'm presuming that the stackcable stuff would be the right way to go if you built up a Euro Buchla 200. If Tiptop's making them to Don's original spec, the outputs should be good for star networking. Since Don was more than familiar with test equipment's musical uses, he tended to use reverse voltage protection, so "starring out" something probably won't have the same results with those modules as it would with the majority of others.
