[sdiy] Roland 191J PSU

[Gergo Palatinszky]

Hi,

2x18V should be ok (ok might depends the load(current) and VA properties of the tr.) but the risk is low .

Br,

Pala

Hi List,

The Roland 191-J PSU is +/-15V but uses a 2x22V transformer.  Would there be any reason why this wouldn't work with a 2x18V transformer?
The design is pretty straight forward, I can't really see why it would need such a relatively high voltage transformer.

I need to replace one but can only get 2x18V or 2x24V.  The latter would probably be too much.

Louis
