Question about Audio Players & Recorders
The power supply was shorted out on secondary side. now only puts out 6.5 volts intead of 13.8?
can anybody put me in the right direction?
thank you Glenn.
I couldn`t find anything on google about the Pyramid 14g.
If we assume it is a transformer type power supply with one output, you may have damaged either a diode (opened) or a resistor in line with the B+ lead.
Your mutimeter may also be damaged, although only the amp measuring circuits should be affected. Measure the output with another VOLT meter.
Since the fuses do not seem to have blown, your transformer should still be ok.
If you are hearing a louder than normal humming sound from the transformer, it is under overload from a possible shorted diode.
Don`t run it this way, until the short is located in the circuit.

It very unlikely the voltage went down. I think you should re measure what the voltage should be yes it 13 volt is after the bridge you wil get this with dual 6.5 volt ac from the transformer, they don't change voltage unless you have a short at the output, and if you did you will blow the transformer, is your reading from 2 wires or is it three wires, output, the center to the end should be 6.5 and end to end maybe 13.8.
I would need to see the schematic to know what voltage you should be getting.
I wouldn't look on a bat transformer but ether, bad bridge or wireing.
I hope this help's
