I wonder why Steve Kennedy sent Mooch a stainless switch housing instead of the copper one?
He said just over 4w loss on the Vindicator, so possibly around 2w loss on the best of the copper tubes - you'd never notice that! It was more curiosity on my part with the copper switch housing as that's what most of them came with, the SS housing is a fairly recent addition (and does look better to my eyes!)To be honest and allowing for differences in machining flaws, looking at the VD over copper ones like the copper Broadside and this one, would you really notice the difference? I forget the numbers, but say the copper Broadside was 0.08 and this one is 0.15, would you be able to sense a 0.07 difference? For sure on the steel RX Machina as it was quite high in comparison but I think his point is well made in that machining and circuit flow design is the bigger factor in performance. I'd suspect most of the VD on the Vindicator is via the two lugs on the contact as shown by the thermal images.
