Now you are talkin'! I had pretty much made up my mind to go with the Sansui from EIFL for about 250$ pr with shipping; they can use either 5K or 7K. Let me look at the DIY units. As far as talking myself into this; it's finding the time to do the grunt work that matters, the parts will all be re-used. Drilling and cutting chassis and mounting tubes and transformers is work. I would love to find someone who has streamlined that process. Thats a guy I would buy even two sixpacks for sharing that knowledge.
