Azelio really just looking at what methods were used back then. That helps me understand what I am looking at at a hamfest. Can I use it and how. I have seen some very nice Gen Rad equipment at bargain prices. Unfortunately I already had the same Z bridge. But it was a really tempting price and unit was in mint condition. But there are many bridges and dividers that show up at $20 or less. So they just add to the test bench. Regards Paul.
