K47 vs K49
« on: May 12, 2023, 06:33:02 AM »

What is the difference between a K47 and a K49 capsule (If any)?

I have a spare K49 capsule (anyway, that is what it says on the box) and I offered this to a person who was desperately searching for a K49 capsule.

But he said that it is no K49 capsule, but a K47. (Apparently he could 'see' this through the membrane, amazing!)
He mentioned that the backplate drilling was 'different'.

The capsule I have here has brass tensioning rings, but according to this person a 'real' K49 should have white tensioning rings.
I doubt this very much, especially because the material of the tensioning rings has changed through the years.

Who can shine more light on this matter?

I will use my laser, to not only shine a light through this matter, but in the process pulverize the claim: the potential buyer is uninformed.

1. You have a 1960s K49 that is actually quite a bit more valuable on the collector's market than anything that came after.

2. Aside of the diaphragm ring material, there is zero structural difference between a K47, K49 and K47fet (prior to eliminating sputtering on the rear diaphragm)

Whatever he thought he saw in the drilling pattern must have been a mirage.

Thanks Klaus! That was exactly what I thought.
