Power Supply Voltages

Hello,

I have built the power supply circuitry, and connected a good AC 16v 22VA (1.37A) power pack.

I am getting exactly +5v, +15v, but only -14.50v for the -15v rail

Is this okay? The power supply circuitry seems okay - no parts get hot when the power is on.

Cheers

It’s within a 5% tolerence so will be fine ;)

Hello All,

Just an update:

I replaced the 7915 (-15v regulator) and now I am getting -15v instead of -14.5.

Cheers
