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.
