I've got a new pyramid ps52kx, right out of the box. It shows 7.8 volts on the meter and the potentiometer will not adjust up or down, no control what so ever.. I did put an old used radio on it and no amps either.
Have you set it up properly ? Consult instruction book. If you are certain it is defective, get a refund under the warranty (if it's new it should still be under guarantee)

Plugged it in, and hit the switch. Right from the start it was stuck on 7.8 volts. I didn't even have anything lined in. Adjustment never worked either. Got it from A-1 telecom 3 weeks ago, set it up last night for the first time.

The manual says you first have to connect the battery and than switch on. You also should take care not to connect a battery the wrong way around (reverse plus and minus) because it could damage the device.
The manual is online:
