Too much voltage from my power supply.
Posted: Monday 23rd Mar 2009, 8:00
Hi Again,
My friend has a power supply made by Pyramid Gold Series. Model Number is PS-8K. Output voltage is supposed to be at 13.8 volts. The problem is that its reading about 23.5 Volts
. We changed the the 2N3055 silicon NPN power transistor. No Difference. The circuit board inside is small about the size of a cigarette pack. Is there anything else that controls the voltage 
? There is a variable pod inside but it doesnt do anything. Thanks Guys...........................
