First-Time Operation - Stereoping Synth Controller Building Instructions

3. First time operation
Checking voltage regulator
Before we put the ICs into place we should
check the operation voltage. Plug the PSU into
the jack. The black ground cable of the
multimeter can be clamped on any of the pots
metalbrackes, they are all grounded.
Now hold the red multimeter cable onto the
left pin of the 7805-regulator. It should provide
+ 5 Volt. If you read 4.97 or 5.02 Volt, do not
worry, it's ok.
If you do not get +5 Volt please check
polarization of your PSU. Middlepin should be
Ground, outer pin should be Plus.
The other two pics show points where you
should also find points to measure + 5 Volt.
