What if you opened up a Manley Reference C and ...

In st51.
Connect PIN1 of male xlr on your mic to 4th pin which is where tightening screw of the XLR is. This way you grounded the body. Make sure screw is tightened, and has good connection to the body. Connect pin1 also to ground of the pcb. Connect capsule backplate to pcb ground, don't connect it to the body. Make sure diaphragm wire is connected to the right side of coupling cap. In the past i made mistake and connected it directly to the fet. Positive lead of the capsule should go the side of the cap that is not connected to the fet.
did all that

Check if the transformer is connected right. Primary should be connected to ground and coupling cap, secondary which goes to xlr should not be grounded!
transformer is connected like it was in the old body. didnt unsolder it.. just unsoldered the connection from the xlr and then back to it in the new body..
Go through this schematic, it is basically the same as st51. Check if everything is where it should be. Check continuity with a multimeter.
as i said im not really able to read schematics i try and it makes some sense. and from what i can read everything should be correct..
how to i test the grounding with multimeter? where do i test it? i checked google but everything i could get was for electrical outlets..

EDIT: resoldered everything again just to be sure.. still the same.. i think i officially give up.. :/

Engineers bash ceramic capacitors because they change their capacitance value as the applied voltage changes.

Engineers know that there are multiple solid dielectric formulations which all fall under the general "ceramic" umbrella, and that you should never use high-K dielectrics like X7R or Y5U for audio signals, but C0G (also known as NP0) in addition to having very low temperature coefficient has almost 0 voltage coefficient of capacitance. C0G capacitors are actually lower distortion than film caps, but single capacitors are only available in pretty small values, you have to make a parallel array in a lot of cases to get the capacitance you need. By that point the C0G array is almost as large and expensive as a film cap, but does have the advantage that they are available in quantity (some film caps have been discontinued or are more difficult to source), and can be manufactured with SMD equipment (important for volume production).

I ordered it the minute they appeared on Ali, they were cheaper. And people were sceptical about ordering it because they were a new company 🤪
How did you get that for 30$? I paid 70€ incl shipping.. but i figured i had to get that just for the looks 😁

So these are actually the same bodies Mangley uses for the Ref. C? Cool eh?


I had to buy one cuz they look cool. Be glad, those of you who got one at $30. They're now $82.13 from Alibaba. No bargain, but I went ahead anyway. It arrived in 13 days.

Electret capsule. In a world where you can get an MXL or Sterling with a full-size condenser capsule for the same price, it's a questionable purchase. But I wanted that sweet anodized pink aluminum.


My hope is this could have a transparent head basket that lets a quality capsule shine without meshy reflections. I dunno if it's open enough. Time will tell.


Thank goodness they shipped it in a silvered paperboard box, because it would've arrived banged up in a padded envelope. (This was shipped in 3 layers of bubble wrap.)


Must desolder ground wire to remove mic from shell.


Circuit board.


They sent an extra free circuit board and 4 screws. They could've saved like 20¢ if they left it out.


Hope that's helpful for anyone else thinking about dropping $82.
