I need a transformer for my resolv 65a monitor

MS16?
Please clarify. What is it.

use a inverter 110 /240 volts in the power supply line
the problem is the different cycles

If you are experiencing a mid-range humming from your monitors when using your Allen & Heath PA12-CP mixer, there may be a problem with the signal level or the cables.
Here are a few steps you can try to troubleshoot and resolve this issue:

1. Check the signal level of the sources that are being sent to the monitors (e.g. kick drum, snare, etc.). Make sure they are not too loud or too quiet, as this can cause the limiter to engage and create a humming sound.
2. Check the cables that are connected to the monitors. Make sure they are not damaged or loose, and that they are properly connected to the mixer and the monitors.
3. Try using a different set of monitors to see if the problem persists. If the humming is still present, the problem may be with the mixer itself.
4. If you are still experiencing a humming sound, you may need to contact Allen & Heath customer support for assistance. They will be able to provide you with more detailed troubleshooting steps and help you resolve the issue.

Overall, if you are experiencing a humming sound from your monitors when using your Allen & Heath PA12-CP mixer, the problem may be with the signal level, the cables, or the mixer itself. Follow the steps above to troubleshoot and resolve the issue.

Compare the power inout voltage listed on the BACK of the speaker and compare that to your current power supply. You have not told us wheree you are or what your power there is... or the voltage listed on the back of your speakers. Giv us this info so we can better help you. These are expensive speakers to get things wrong...

Transformers RARELY fail. It is likely that either one side of the amplifier has shorted or there is a failure in the rectifier/filter circuit of the power supply. Take it for repair unless you are adept at electronic repair. Do NOT continue to replace the fuse as you MAY cause futher damage. Use a 25 or 40 watt lamp in series with your power cord to limit current while troubleshooting.

Did you just use adapters or actual step-down transformers?
A lot of equipment today is 110/220 auto-switching, but if you get something built for 110V (120V, 100V, markings may vary) only, then you need more than an adapter, you need a transformer!

Google ,,,Pyle Ppg460a And ask,,Where to find Pyle Ppg460a transformer? Alot of places will come up just click on them untill you find the one who sales them,,,Also Go to weber speaker ,com and they have a amp forum and you can put the question there those guys know everything,,,Also they sale replacement but not original transformers there,mabe there is one weber can match you up with, Good luck

The winding is center tapped. It generates +/-24.5 volts DC. Based on it being a capacitor input filter, we need a peak voltage about 1 volt higher to account for the droop of the capacitor and the .7 volt drop of one silicon diode...

Since we need 25.5 volts peak then we need that divided by 1.414 RMS out of ONE side of the center=tapped secondary... So our secondary voltage is 18 volts either side of center.

You will need a 36 volt center-tapped secondary. Here is one that would work:

This has two 18 volt windings that you would connect in series and a dual primary you can set for either 120 or 240 input. About $19 US.

This is just a hint as I was unable to find the schematic. Transformers VERY seldom fail, if you are getting anything out and the fuse is holding with no heating, the voltages are probably right.

Common voltaages seen after the rectifier and filter and regulators are +/- 15 volts and sometimes +5 volts. For the power amp they are usually between +/- 35 and 60 volts unregulated.

For small amps using the TDA2050 type amps, you will see aproximately +/- 24 volts DC unregulated.

There are MANY more likely components than the transformer that will cause the fuse to blow.

Most common are filter capacitors, rectifier diodes, and shorted components in the power amp section.

Transformer failure is very UN-likely. Have a competent electronic tech troubleshoot the unit.

When testing the unit, put a 150 watt light bulb in series with the power line... saves fuses during troubleshooting. This limits the current so one can analyze the real cause of the problem.
