M49c Build p2p in Flea body.

[Frank00]

I'm not sure that it will be an upgrade. I like U47 (and Flea47) a lot better with M7.

I like m7s as well, but some Flea 47s with the stock capsule just sound weird. They have a big dip in the presence range (around 5k) that makes them smooth, yes, but also very soft and colored not in a good way.

 

[Frank00]

A genuine K49 in an M49 clone is a better alternative.

Yes, that is a great combo for sure.

 

[Frank00]

We bought a lot when it was available

God damn David, you’re one smart fellow. And I know you’re not letting those ones go easily

I've only heard them with Theirsch M7. Nowadays I think they use their own M7.

Yes, I pretty sure they do use their own capsules. They do the metalwork and thiersch skins them, afaik.

How does a Thiersch M7 compare to your vintage M7 reskinned by him? Have you had the chance to compare?

We will do that test this weekend (m49c/ac701, Poctop, Rico, vintage Gefell m7's)

I like M7's too. Sort of wish there was something inbetween the 3U and Thiersh blueline, both of which I have experience with. I love the low end bloom of the Thiersh, but like the smoothness of the 3u in the high end. Maybe it's the Redline I want.

Anyway, would love to hear the results of your test.

I have two new Chinese M49 bodies that don't fit with any of the current round pcbs

I recently bought two of those Chineese M49 bodies and one with Binder, fits 60mmØ Disks/PCB's.
Hit out David (@TLRT ) he has rectangle PCB's for those Chineese bodies and also sold me nice acrylic disks that he made for my other Binder body.

Please publish the results! It’ll be interesting! Maybe throw in a Neumann k47 as well, just for reference.

Here's some PTFE discs from China https://www.ebay.com/itm/2258716037...x4UO/9gXcQE3sOCb59yNKID64=|tkp:Bk9SR-qp8sG7Yw

They can be ordered in 55mm, at various thickness. What is the procedure for inserting turrets? do you just drill a hole and push them through?

Also, PTFE is more toxic than FR4 turret material. Is there an advantage for the Hi Z section in using PTFE?

Yes I do square ptp panels for those smaller m49 bodies

Aren’t k47 and k49 basically the same capsule?

PTFE is actually not really toxic. The production process with these Poly and Perfluoralkyl compounds "PFAS" and contamination of the soil or groundwater with these ecologically non-degradable substances "forever chemicals" is the problem. Substances such as Perfluorooctanoic acid ... have been far too little investigated for human and environmental toxicology. In Belgium alone, 3M has to invest 10 billion !!! euros to recultivate highly contaminated groundwater in the area of a PTFE production factory. Incredible sums, but also a multi billion-dollar business for the recycling industry. Gendorf/Trostberg in Germany/Bavaria is also under big Observation of the German Gouvernement. Most Deer like Wild Pigs in the surrounding area of dozen kilometer circle are contaminated and forbidden to eat.... All airports with proven halon extinguishing operations are also under fire from the authorities. These “PFAS” scandals are reaching unprecedented proportions. It is an exploding scandal worldwide and happens if science is not done properly....
I think it is a good time to buy the last available PTFE coated Frying pans For people who are interested in this subject:

K47 has one diaphragm connected only(those are k49 which one side out of specs)

PTFE is not really necessary,standard Plexiglas has minimum 30Kv per mm dielectric strength and super high surface resistivity

there were originally 3 designations according to martin schneider. a u47fet capsule only has one usable side in spec. a k47 is good enough for the cardioid and omni, but not good enough for figure 8. a k49 is good enough for figure 8. this was simplified to 2 later and then 1.

@soliloqueen, didn’t you have plans to do a vintage Neumann style (not flat) K49 capsule? Is that still in the works?

It's done. We're going into production after I finish setting up ARTA. I'm planning for it to be a little bit more of a premium capsule and it's going to be our first fully serialized run (ideally)
