This comes from the new version or the old one with cable? How about FR?
Sounds interesting

So BAIFEILI did a 414... with a mono diaphragm capsule... which is not in CK12 style but U87... ?
Gosh...

That's the nice thing about this thread, you can see what's really inside.

BTW, the front- and backplate hole patterns remind me a lot of the standard capsules used in the t.bone SC450 and similar mics.

Hi @pasarski how does it sound ? how much it costs ?

Ok, the $20 ali K47 didn't sound particularly good. It has a quite pronounced middle peak and lacks low end as well as air.

Here are some pictures of the 1st generation of T-Bone SC1100 :



This is 20 years old and has some dust on the capsule, working great though.

Which one did you get?

This. There was a even bigger discount when I bought it. Probably for a good reason. It's also super sensitive to plosives.

I don't know . . . that could still be an Okatave capsule, just with a decorative ring covering the screw heads. It looks to be an aluminized diaphragm, like the Okatavas have.

Well, if the OP is allowing ribbons in the clubhouse . . .

- Oktava ML-51; an unusual mic for it's time (mid '70s), in that it had an active battery-powered 'boost circuit' in it. Motor shows some influence of RCA ribbons.

- 'Trix' (which had the same motor as the Film Industries M8), with it's triple horseshoe magnets, and unusual ribbon corrugations.

No problem, ribbons are very welcome!

Yes I got a pair of these too... Still working... Built as a tank (and as heavy too)

I’ve had one of those for many years, in really excellent-shape, on the outside at least, but I’ve still never used it. Still have to put an XLR on it. I’ve seen people say pull out everything, including the battery, others say use it as stock. I don’t know.

I gutted both mine and put in Edcor transformers. They sound fine, but I've never had any mic pres with enough quiet gain to use them for anything but close mic'ing, which I rarely do. Used them only once on a loud percussion soloist.

The boost circuit is very noisy and harsh; have a look at the thread I linked to.

Yes, but the hole pattern is different and i guess some things have changed after 2004, when manufacturing was no longer made in Latvia. BTW - they are now part of Logitech…
