C414 "Comb" version
gtoledo3:
Point taken Klaus, and thanks David, Brad.
I was looking into something else today and happened to notice a document that clarifies something above:
https://www.akg.com/on/demandware.static/-/Sites-masterCatalog_Harman/default/dwab2b98cc/pdfs/CMSE.pdf
So, correcting/amplifying a point above; “E” stands for XLR connector, 100% certainty.
At some point after the initial C451, the AKG catalogs begin to list AKG C451C as well as C451E, in addition to CB, EB, and 452 variants. The catalog description states that C in this position (post numbering) is a DIN connection, E is XLR.
I may put all of the substantiation of the points mentioned earlier in the thread, in a dropbox folder or on imgur at some point.
edit: Oh, I now see the attachment field I failed to notice earlier. Many points were covered, I’ll try to post some of the more relevant stuff in the near future. And it is nice to see even earlier examples David!
David Satz:
E = export = XLR
C = continental = Tuchel (back then)
L = Lemo for the ÖRF (Austrian national broadcasting network)
which could be combined with:
B = bass control (low-cut switch)
so EB = microphone with XLR output and low-cut switch
452 = 451 with one resistor different, so that current draw at 48 Volts would be somewhat reduced (it was about 5.5 mA for the C 451, back when the DIN standard was still 2 mA maximum). However, as a result the 452 requires 48 Volt powering, whereas the 451 could accept 9 - 52 Volts. And even the 452 required ca. 3 mA. Back then, AKG and Schoeps' Colette system were like "outlaws" until the DIN standard was revised to allow a maximum of 10 mA/microphone at 48 Volts.

I was reminded of this thread today when looking at these fraudulent Reverb listings for C4 heads and brass CK12.
The seller has obviously taken a red band CK12 from one of the C4 heads they have for sale, and is choosing to inaccurately describe it as from C12/251: https://reverb.com/item/51525768-akg-brass-ck-12-red-band-c12-251-capsule-1960s-brass
In my book these should be at a much lower price, and definitely not described this way.
And here are the C4 heads…for some reason with “Teflon” CK12. What a “coincidence”!

Oh yes, surely a "coincidence" just like the mad price.
Peller:
Did the CK4 head ever come with brass ring capsules? I thought it only ever came with the nylon ones.
Either way that listing is taking the mickey. There was a seller on UK eBay a couple of weeks ago who auctioned three pairs of CK4 heads, I think only one of the auctions went above £1k.
