Hi,
Somebody knows if an older IMSAI power supply model PS-C rev 1 can be wired for 230V? I don't have a manual for this model.
This PSU used the TRANEX 4-3751 transformer that seems to have one primary winding with 4 lugs, nr 1 to 4.
Currently AC mains is on lug 1 and 3 for 115 v.

Thanks,
Wilko
 
Sorry, I already saw that the answer is in the manual I have, a few page further. The 4-3751 transformer is only 115v and the extra lugs on the primary side are for +/- 10% line voltage adjustment.
