So I think that the historical explanation for the high prices, and the long duration of certain product designs, is based in those purchasing patterns. Even today, you and I--who might buy one pair of capsules after agonizing for months and talking it over with our therapists--are up against the market influence of customers who get authorization to buy 100 or more microphones in a single swoop, and who want the accessories to be part of the same order.
I feel this ^
--The present-day A 20 was actually introduced as a more robust type of shock mount than what Schoeps had made in the past (see attached photos from the 1965 catalog; I used to have some of these; the sleeves surrounding the microphone body were thin metal). Their design was patented, and I think Dr. Schoeps felt rather proud of them. But Jerry Bruck complained about them and actually had the nerve to demonstrate the problem by stepping on one and breaking it in front of Dr. Schoeps--who was taken aback, but he got the point, and the present form of the A 20 (and related models) was then designed.
I love this story very much! Total respect for Jerry!!!
Since then, the inner part (the actual "clamp") has been replaced with a newer type of plastic that is much harder to break and that doesn't risk scratching a Nextel finish nearly as much. The plastic "foot" (the only part on any of mine that has ever broken) has also been replaced with metal.
Funny that should come up. After years of service, the base of my A20 gave up. The top cracked off of the base. I got out the micrometer, did some measurements and hit TinkerCAD. Had to tweak, but the 3rd prototype was money. Printed with PETG. Very strong and threads smoothly onto the quick release (not shown) I always used with it to help prevent wearing out the plastic threads. I'll probably end up printing one more using settings for fine printing.
I'd be stoked to have a replacement thread part if you are running them off! Mine is split from years of use, and I have had to find other options. This would rejuvenate mine! Will gladly pay postage & plastic cost LOL!
