Default Do SOLAs go bad?

Sola transformers were made for all sorts of output
voltages. The caps do go bad which changes the volage at
the
output and can prevent the transformer from regulating. I
also have a couple of old Sola's which do not regulate at
the correct voltage despite new caps of the right value. I
have never been able to find out what causes this.


Most probably load. These things MUST be loaded to half
the rated
maximum load for proper regulation.

Note that the capacitors must be non-polarized types.


Film caps are recommended.

These don't regulate at the correct voltage regardless
of load. My good Sola's have just about the specified
voltage open circuit.
