Tried this acrylic thing for the first time, satisfied with the result.

Absolutely fantastic ...

What kind of acrylic did you use ? I don't know exactly, but I think that I read somewhere, that not all are suitable because of poor high ohm isolation...
Is this 5703 tube ?

Thanks! No idea about the kind, just bought it at local hardware store. I used 120 meg grid resistor, and high pass measures as calculated, so i guess it's well above that. The tube is 6s26b-k.

I found the video interesting as well and am now a subscriber. BUT! As I was watching I heard some faint and strange (to me) audio. I thought for a ment that somehow my system had developed Radio Frequency Interference. Glad I learned the truth before the video was over...

Looks very good. If you don't mind some questions, what kind of turrets did you use? And what polarization scheme did you go with?

I used these, removed the plastic and snuggled them in the holes i made. I cut the upper part in half.

Capsule front direct to grid (0v), backplate 60v, rear variable via psu.
Here's a sketch i used for build. Never meant to share it, i just drew in one night at work based on the originals, and added external pattern control.


Edit:
I added 120Meg and 15nF filter before HiZ pattern control resistor due to some low end buzz.

My friend and I managed to fit Poctop’s PCBs in these great but short bodies. Thanks to Herbert and his skills we were able to.
Beesneez capsules sound so authentic and I bought a Job lot of NOS GE 5 star. Needless to say they sound superb. Thanks for all the guidance!

What outpout cap type did you end up using?

The most accurate capsules I can find are the aluminium Beesneez ones. I chose them over vintage AKG ones they are that good.

I am just now measuring two of the Beesneez CK12. One is so beyond spec that i don't even want to comment on it. The other is at least 3db brighter than brightest Tim C's capsule. They are also deep dish (bright) variant. Unless you have some kind of special handshake, or special dark sounding capsules ordered from Beesneez i really have no idea what you are raving about. How could they be accurate if they are aluminum?

I've always found my BN CK12 in a 251 to be too bright. I finally have a room where i can get a half decent measurement and see that it measures incredibly bright. I have two C12s with TC CT12s and the BN CK12 is in my 251. I put the BN CK12 in one C12 and compared the two. The BN CK12 was waaaaaay brighter, in an unflattering way.

The 251 sounds great, but too bright for my use. I always thought I would find something that it works on, but only on the occasional guitar the 251 would be selected. I emailed Ben and Veronica but no response yet. I'm working on plate filter to make it more to my taste, but that introduces a lot of phase shift.

I'm not interested in bashing BN, i've had a few of their products on my bench and i was not impressed. Fiddling with their CK12 for the first time. And i can promise, these are not superior to others available in any way. I could go balistic and share the images and measurements, but as i said i'm not into starting a war right now. They are a family business, people seem to be satisfied with their products, so i don't really care.

I have had great experiences with them. Their K67 sounds amazing and their M7 is my favourite capsule for vocals.

I suppose there is a lot of variance in CK12 capsules, and each CK12 manufacturer has a different favourite CK12 capsule for reference. Either the CK12 sound Beesneez is going for is not my style, or there is something off with my particular capsule.

I wait for a while and get a perfectly matched pair. This has happened twice in a row so I don’t think it’s a fluke.
I also have a pair of BC12a’s which are interchangeable with my c12a’s. My 47’s are spot on too.

Weird, I have never heard a TC capsule I don’t find too bright. I’ve heard Haun’s that are dark but take eq well and sound fairly authentic. Tim’s just sound glassy to me.
However Ben’s sound spot on when I install them.
