Suitable transformer

Post by cheshirenoir » Mon Jan 09, 2023 1:04 pm

I'm obviously a sucker for punishment...
Now I want to replace the PSUs for the CVs :-D
(Yes my Hanimex has no PSU)

I was thinking this Transformer should do the job, assuming it was cased suitably...

Anyone one with more knowledge care to pipe in?

Hi,

the original transformer uses 2 independant secondary windings and not "center-tapping"...
There are different versions of the CV mainboard with different internal PSU schematics.

Short: I do not know, if all CVs (Hanimex) would handle the Centertap well...
I seem to remember that someone here in the forum fried his CV...

To be on the safe side i would use 2 separate smaller transformers (this is a well tested approach)

Cheers, TOM:0)

AFAIK all 220V creatiVisions use interchangeable power supplies. Which means the Jap and US models have different power supplies (the Jap uses a DC psu, the US uses AC psu).
And I agree that 2 separate transformers would be the best approach.
