Transformer output Can I use a transformer with a 15v 2 amp output in place of the standard transformer which has a 15v 1 amp output?

Well, first off, if this is an IC output, depending on the rated watts per channel, you will certainly need a rail volt greater than + - 15V. That would be for a regulated voltage somewhere else in the amp.

here is a link that may help you with your problem.

the prq can be used after a head unit before crossover and amps. it is a preamp/equilizer and you must have an orion amp in the signal chain that uses the 5 pin din plug to provide power to the prq via phantom power. if you have a crossover it must be a brand with the same 5 pin din pinout input and output. the din pinout is 1\+15v, 4\r. ch input, 2\ground, 5\l. ch input, 3\-15v. left to right or clockwise on din. the power can be supplied to the prq with an optional 100 pps power supply unit. rca from head unit feed the input and the 5 pin din is the output .

Try to download the service manual to sony ICF 212, from internet. It will have all the details.

If the DC is 15v then the AC is around 12v.

The only simple way that I could think of is for you to purchase a STEP DOWN TRANSFORMER rated at 500 watt, 110 volts, 60cycle. The transformer inside that amplifier have four output 12v and 15v DC.2amps It will be hard to get the transformer for that! Hope that might help you! taah!

You have to do the math according to the circuit path, and all components in between. Break out the voltage meter.

Make shure with an ohm meter that the primary and secondary windings have very little resistance on the main trasformer,then check voltage in trasformer and out from transformer...BIGRED
