Vintage Synth Repair

Hi,

get hold of the synth first, or attach the required schematic part if 
possible, it will help things. When the power transformer fails, there 
often is a problem somewhere else.

If it outputs +15v and -15v, the transformer could be a 18V-0V-18V, as 
diodes will rise the voltage up to 1.414*AC voltage.

There are many different types of transformers, different sizes for each 
of them, and different ways to connect them.
