First of all, did you test the primary and secondary leads for resistance? They all should be from 2-30 ohms max. If they are, the transformer is fine. If they are open, you will need a service manual which may be on-line. If you need more assistance or would like to inquire about repairing your unit, please visit my website at audoserviceclinic.com. Thank you.

Is power coming out of transformer at the right voltage. Also may have a power i.c. shorting to ground.Final anp i.c. may have a place to go to ground through a shorted capacitor.

I would contact Sherwood as Transformers are deemed to be safety components and should be replaced with excat parts or those recommended by the maker.

What is the output voltage of the mains transformer for the Onkyo SKW 770 Subwoofer amplifier? I need the specs so I can have a custom replacement toroidal transformer made. Thank you kindly in...


It would seem that a call or email to the mfr, should be your first move.
Are you certain that the transformer is at fault?

Power supply output for Yamaha p4500 secondary output for the power supply so that i could check the voltage


Hi Joel, although we've sourced detailed schematic for this P4500 amplifier, there are no many voltage details on it for manufactures sake. Anyway, mine findings are. Secondary winding on main transformer should supply no less than 2 x 75 volts which makes after rectifying and filtration no less than 2 x 90 volts on capacitors with amplifier without input signal. Also transformer has to be very "hard" , otherwise amp will start clipping before reaching stated wattage on output.

No audio output or output voltage on 70v terminal


it sounds like you have a power supply problem
try and check for a blown diode inside close or
around the transformer.
maybe this will help.

What are the secondary voltages off the transformer supposed to be?


The secondary voltages of a transformer are stepped down voltages. For example a transformer might be stepping 120 volts AC down to 25 volts AC in the secondary. Which then would be rectified by a bridge rectifier in the power supply and converted to DC Voltage which would be used to bias transistors or tubes and other electronic components. The amount of voltage that is output for use is determined and calculated by the engineers designing the amplifier or pre-amp.

If it has a voltage selector switch it to 208V or whatever is closest. OR, buy a transformer that converts the local power to 110V.

My Onkyo Receiver TX 601 is turning itself off


Several things can cause this: Loud signal passages can momentarily draw high currents at the mains, especially if you have unit plugged into power stripe with other equipment. Or if unit is plugged into isolation transformer, current draw may exceed output of transformer. Too many speakers hooked to output or if one is bad (partially shorted due to overheating)

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
