I Need A Power Supply For An Oktava MKL-2500?!?

[ghetto3jon]

hello. i have an oktava mkl-2500 without a power supply. does anyone know where i can get one? (i also have a mxl v69me...is its power supply compatible? i doubt it, eh?)

thanks.

I highly doubt they are compatible, however I am sure it is possible to rework it to fit both mics.

what do you mean "rework it"?

Most likely both mics use the same voltages, but connectors have different pinouts. There are three ways to do it. 1) To change internal connection in your Octava or 2) To drill another hole for additional XLR 7 pin in your PSU to work with Octava 3) to make an adapter for Octava, which will reroute pin assignment. Your Octava might need some tweaking if the voltages are little different.
Without schematics or seeing the mics and PSU, it is hard to say exactly what to do, though.

You're very lucky info like this is usually very hard to come by - google is your friend

Now all you have to do is check the wiring of your v69 supply

Yes, I remember Stewart posting it. The problem is that, IIRC, there were a few versions of MKL2500. The one on the schematics is a cathode follower. There also was one as an anode follower. I didn"t see its schematics, but it might have different capsule bias arrangement, pinout, and B+ voltage.
The filament is way underheated. The 6Z1P is a 6.3V filament tube, so you can use usual 6V, most Chinese tube mics PSU deliver.

Marik, you are a fountain of knowledge!

Hey Jon, try to draw a schematic of your mic if you can or take some *detailed* digital photographs and notes of the innards and we could maybe draw one for you. This kind of info is usually hard to come by and could be very helpful for others
