that looks cool!

I'd build it as is first and see what it sounds like but some nice components like a cinemag transformer, upgraded capsule and high quality parts upgrades (like a better 7 pin cable, PIO or Wima caps and high quality install wire) could easily make this mic sing and dance on the cheap...

If you are comfortable with a soldering iron, 100 bucks is a VERY good deal.
I spent 150 bucks on a pair of brass mic bodies alone.

have fun soldering and cheers!

I saw that too and here are my thoughts.....to make anything decent out of it you will more than likely have to change the circuit topology of the mic....not to mention the power supply....then there is the capsule to deal with. Seems like a crap shoot to me at best. I suppose you could build the mic as it is supplied to you and if you like it more power to you !! Too many unknowns for me....

For 100$ I'd give it a try. I personally don't have 100$ to spend on this, but if I did I'd be willing and eager to try it out!

Get, put it together, then post the results here! :D

FWIW: a lot of the chinese mics are actually very competent and useful designs based on such circuits as Neumann and Schoeps. In my limited experience, I've noticed that it is the executive branch of manufacturing that will take a nice design and proceed to hack it apart with shitty and poorly produced parts and machining.
Thats why this kit is 100 bucks.
Not because its a piss-poor design, nessesarily, but because the parts and machining are, more than likely, el-cheap-o.

Also, if the PS doesn't have a very low ripple, has bad or undersized filter caps or you want to tweak the design around a different tube, I could see screwing with the PS.
Otherwise it very well might be useful as is...no need to crap on it yet...

I do agree that without putting it together and listen to it, no one (except for the mics designer) has a clue how it will exactly perform.

Cheap tubes, cheap transformers and cheap capsules and cheap circuit components are first swap-out priority on my projects.

but to each their own...


cheers!

I looked for reviews on their Aurycle tube mics as I'd assume the DIY are of at least similar quality but haven't found much info. I didn't look very hard but if you do find predominantly good reviews on their assembled microphones it might give you a little more confidence in this DIY.

I might be nuts, but some of those caps look like Panasonics which is a good thing... Throw away their tranny and capsule, get your own (Cinemag/Peluso respectively) and it could be pretty awesome as long as the PS isn't total crap. It's really hard to say without seeing it all.

Thanks guys for your thoughts..
They are about the same as mine are..
For sure some mods (Capsule, TUBE!!!, and the other)
Just a good start.. Im going to see if I can get ahold of more info and/or pics, schematics and all sort of things..
If I decide, you never know.. its probably good how it is.. Sound Samples with be shared, hopefully good.. and lets see how it goes..
Will keep you updated..
..More thoughts are also welcome..
Thanks everyone and God Bless...

That looks like the bits that make up an MXL V69 - having pulled mine apart a few times.

did anyone from here buy one of these? I would be super curious to see how they are, seems like a great and cheap way to get something worth modding.

The key piece in all this is the capsule. If its decent then the mic will be but it shouldnt be too hard to simply replace it should it not sound the way you want.

Capsule and transformer are the things that effect the sound in the biggest way I believe. Good luck on these.

At the published eBay price of $119.95 plus $17.81 for shipping the capsule would most likely be an Alctron 32mm K67-style as found in the Apex 460 etc. Even the least espensive Peluso K67-style capsule retails for $130. But a flatter K47-style would be a better choice in my opinion.

I suppose one way to look at this kit is that it is a few dollars less expensive than buying a new Apex 460 to use as a mod platform. But the buyer is not going to get a capsule of the quality offered by Neumann, Gefell, AKG, MBHO or Peluso (nor capacitors of Black Gate or similar quality, nor transformer...) for that price.

He's got a tube SDC on there for $50!

I might get a pair and see what they sound like. At the least they could be modded for fun, right?

Ah, its a "true" condenser (to distinguish it from the $50 Behringer C2 electret SDC I suppose) - not a "tube" condenser. But yes, $50 plus $18 shipping and handling does make it a couple of dollars less expensive than a CAD GXL 1200, Nady CM-90 or MXL-603 which share the same capsule interior and circuit design.

Oh whoops my bad, yeah I read that as "tube." Well I already have a 603 pair so that probably wouldn't be any use. It does have the low cut and attenuation though which is nice, for something so cheap (if you want those features, I usually don't).

I bought one of these, I got the kit yesterday.This mic is the same circuit as the apex 460 but with the cathode follower already removed, and it is not multi pattern.

I plan on replacing just about everything on this mic, I will post pics and info as I do it. It may be a little ways out though.

It looks like it could be an Alctron HSGT-2 Same body shape and radiused headbasket cut-out corners. Appears to use an 18-Philips-screw capsule which is a halmark of Alctron's 32 mm capsules.

I like how this Aurycle mic uses a single layer headbasket like my MK-319 Floating Dome. The other recent single layer convert is MXL with its "Gold 35".

Bumping an old thread

Going back to reading up on the Aurycle SDC's, I'm tempted to get them. With a discount, I could get a pair of these for less than $100, and they have low cut/and -10/-20db pads. I assume they would be the same or around the same ballpark as MXL 603's, but I've no experience with these. Anyway, should I either do this pair, or get an Apex 205 (~$100), or Nady RSM-4 ($70ish)? My primary concerns would be drum room/OH mics, and acoustic guitar. I already have an Apex 480 LDC, and a SM57.
