Ela-M 251 Body from Aliexpress

Darn I was thinking of using it for my hydrophone project

Maybe but it is also much easy to work with (acrylic is brittle), totally heat proof when soldering, helps to maintain things clean of flux, and the most important a much better dielectric.
edit : Can i use / modify a chinese tube mic power supply with pattern switch for this project or am i forced to build Poctop's PSU ?

Of course you can. This is a DIY site. Nobody FORCES anybody here (at least I hope). And I have done it (modding PSU).

You can either use a smaller Chineese PSU at 120V. I ordered one just this morning. Add pattern switch, easy.

Or modify one of Thomann’s - T.bone power supplies. You will need to lower voltage (two parts to change) maybe filter better the output voltage & ground it better. Fellow GDIY members went on at length on how to achieve that.

You have a link ? or a schematic ? I already have two T bone retro II PSU from thomann

Link here - 30 bucks a piece for 120V PSU - Chinese made with prire.

Schematics below. Red circle/oval (change parts) and red arrow (polar patt).

Anything else... would you like some sugar and milk with your coffee Sir?

No milk thank you ! Le service est impeccable j'en ferai part à la direction

Hey Garp!
Cool build but how did you do the black rear grille?

 

[garp]

Spray paint Satin black for bike exhaust, masking tape bake in the oven et voilà !

Got mine done. Such an impressive sound, look and feel of this microphone. I'm going to record something with long phrased vocals and acoustic guitar ASAP to demo for real, but wow. Is this self biasing? Did I read that, in a thread? If not, where do you measure from? Did a fast spoken demo late last night, no vari-mu compression this time. Straight into the hardware, no eq, just mic.

This was a scary build for me to get started, with it's point to point section. HerbertR is wonderful with his documentation which I followed (3U Tx, Beesneez Capsule) but I have the 250M grid to ground and a 1uf PIO in there. Herbert, I'm listening closely to see if it's too bassy, but my C12 def has more, and I'm happy in those frequencies, but does it have the sweet mids you referred to? I have no basis for comparison, only youtube.

Nice ! Did it come with the E on it ? What circuit did you use, and on what support ? Where did you get the shock mount ? Lots of questions

Yes, body came as is (heavy as hell too). Both body and shock mount from Ali Express. Dany's D251 boards but make sure you read through this thread. Lots of modifications needed to make this fit. Not a lot of direction with the power supply, but it's damn close to Dany's C12 P/S and photos got me the rest of the way there.

 

[thomasdf]

Do you have a link to the shock mount ? The ones I found were slightly too large iirc
I will probably go ptp / turret for mine.
It’s funny because my bodies came without the markings. Prob an older version.
Cheers !

 

[geekmacdaddy]

Sure. Know that it just about gets in there, but does fit. https://www.aliexpress.us/item/3256...t_main.30.3f561802wMWc4s&gatewayAdapt=glo2usa
