Universal Ultra Power Supply

Pitts256:
Anyone have a power supply schematic for a Universal Ultra Upright model 94000?

Pitts256:
Well my worse fear has become reality.

My Ulltra power supply failed a few weeks ago.

A darlington array (see picture) has overheated and failed.

If anyone has one of these or a failed power supply with the part intact please PM me as I would like to repair mine. To date I've had no luck finding a YEC YD-1310 or a data sheet to fit a suitable replacement.

At this point I'm going to assume that a replacement part is not available so I'm reverse engineering with the data I have and will be putting together a replacement power supply. For those of you that are in the same situation with a failed power supply...I should have the complete assembly made up within the next week and I'll post a file with the instructions on the build; pin outs, parts list, pics, voltages etc.

May want to try calling NLG headquarters in Bullhead City.
Back in 2019 I sold them all my Uni stuff including good and bad Ultra power supplies.

Pitts256:
Thanks

I'll do that.

New Power Supply Update:

The new power supply project went as planned.

The Super Mag 7 is alive and well.

Still putting together the build file. I'll post when completed.
