I finally found/bought a local pair of SDA1B
So I may have to finally retire or sell my 2b's after about 15 years of faithful service.
The 1b's sound very much like the 2b's but a little bigger sound stage. They didn't sound a bit harsh especially since the right 2 tweeters didn't work :D
Instead of swapping tweeters from the left speaker, I pulled a used sl2000 off the shelf that I thought worked even though it had a loose terminal. No go so plan b to bypass the polyswitch.
Done, still no tweeters. Pull another sl2000 off the shelf, one of doro's surplus :). Magic silk heavenly sl2000 emulsion at last and still not a drop of harshness. How can this be. Oh well for kicks I cup my hands around each tweeter and sure enough the top one sounds a little harsh. The bottom is not harsh due to its different crossover point.
So here comes the caps. The 2.2 was too dramatic and lost too much of the sound stage. The 1.0 was just right :p
Left (cap) vs right (no cap), the right still sounded better but I figure I better tame the harshness a tad in case any polkies with their hearing aids turned up too loud stop by so I put a 1.0 in both top tweeters for now. Still sounds great.
The seller claimed all the drivers and tweeters were working but he had nothing to demo them with. I'm not going to hassle him since he's a mp in the military ;) and I got them for < $300.
The vinyl is not in as good condition as my 2b's but these don't have any dented dust caps.
