I have the same PSU,  that is on my shelf, waiting for repair.

The schematics would certainly be useful. I will see what I can do with the french site, but although the post is old.

I checked mine. Its exactly the same outfit, but model MC1050  should be 10V  5 A.

If you get the schematics of the MC4020,  I will be interested.

Fine,

I checked my MC1050.  The voltage is fine but the current limit is erratic unless it has heated fo a while. So I will have to do some repair.
A the  case is exactly the same as yours, I imagine the inside will be very close.

Thanks.

This will push me to restore my MC1050 to its full state. It impressive to see that this 50 yr old device is still working. I checked some electrolytic. They were all fine.

My multimeter doesn't have capacitance to check them but it seems like it's in good working order.i guess that since it doesnt look swolen or leaky  or fizzes it's ok.
