Power board

yesterday I bought some parts for the power board. Fortunately I had most of the parts in the junkbox.

I need several voltages.
5V for the microprocessor and the divider in the tuner.
12V for the opamps.
-12V for the opamps.
24V for the tuner.
30V for the opamp that drives the varicap in the tuner.

Last night I added to the power board 5V, 12V and 24V.
