Thanks mate,

I've tried a tirodial one  220v to 2 x 24v but it makes the output be very noisy.
Noise from the mains ofcourse, so i decided to put back the 100 v
transformer and use a step down converter.

Will so how this works. If still with troubles, I'll try out your
suggestion.

So thanks a lot.

Razvan

Which reminds me...

Almost every Polysix and Mono/poly I find here in the UK needs a new
transformer. The old ones become lossy and generate a lot of excess
heat. It will take it hours to warm up but it will and if left on will
cause enough heat to warp the patch button PCB. If your patch buttons
sag in the middle section your transformer is probably getting too hot.

This may well be just a UK thing since we typically use 240V which does
have a tendency to push old and cheap transformers to their limit.
