Default Moscode Super IT - schematics? power supply?

Hello DIYers...

I have recently come across two NYAL Super IT phono preamps. Both are in pretty rough shape, a little rigging, and no power supplies.

I would like to restore them both to as new...

Does anyone here have a schematic they would share, or have any technical info they can offer? Can't find much on the web about it.

Thanks
Caleb

Question Super IT Schematic?

There have been posts and threads for years with people asking for a schematic for the NYAL Moscode Super It, and it seems like NOBODY has this. George Kaye and Moscode seem to no longer exist, or so it seems. So, does anyone out there have it? It seems amazing that it can't be found anywhere on the internet. Mine keeps blowing one of the big power supply electrolytics, and I know others have had this problem as well. A schematic sure would be nice... Anyone? Thanks, JV

I know I have it somewhere and I know I found it on the interweb. I'll try searching again.

Default Super it Fuses

I lent my Super It to a neighbor years ago. After it was returned I put it away.
Now it doesn't work. I see that the fuse by the filter caps is missing. Maybe it blew and he never said. In any case I was wondering if you knew the value of that second fuse? ..and, no, I don't have a schematic. Darn!

Hi Spinning Wheel:
Thanks for the circut diagram, however still no value for F1. I measured the draw and it seems about .08A, so I am thinking a .5A fuse might be OK. In the meantime I found the HV filter cap was bad.
So waiting on that too.

Just pulled F1 out of it's socket , it says 250V 3/3 1/4A
So 250 mA .
Note that I'm located in Europe ! not sure if my adaptor is similar to
the 60 cycle mains used in the US ?
