AKG N6128/23

[Walrus]

As per subject, does anyone have a schematic for the AKG N6128/23 power supply. I've tried a search, but came up empty.

I am also looking for a schematic for this supply

searching only led to a post that was taken down.

hence a big bump from the past.

The AKG N6128/23 was used to power the C12A right?

Then maybe it's just another designation for the N12a PSU..? The N12a schematic is drawn in the C12a schematic.

it is switchable, 5 Volts for a C-61 or C-12A  or 6.3 Volts for C-28 or C-12

and about the oddest connectors on the back i've seen on any AKG supply yet.
this one was for the domestic market, as it is 220V

this one will warm up a C-61, but virtually no audio.
(very faint and nothing below about 2k)

If it works with a C12a, it should work the same with a C61... Are you sure you are talking about the C61 and not the C60? The C60 needs and output transformer which is located in the PSU, this could explain the 'virtually no audio'.... In this case thought, I'm affraid the 5V DC would have warm up the AC701 a little too much

it's a C-61, tried 3 of 'em, couldn't find any of the littler C-60s at the moment...
don't know what's up with that, i don't even know how many mics
we have any more
i should just put a meter on the ins of the pwr sup and make sure
5 V is there and really V.

not much inside these things...

Very strange indeed... Can you confirm that the C61 you tried are working well when connected to their dedicated N61 psu?
And that your NG6128 is working well with a C12A, a C12, or a C28?
