Power transformers are safety parts and should only be replaced by the same type or one specified by Eltax the maker. You should contact them for the spare parts department or the place that stocks them.
What??? There is NO output transformer for the Mg50DFX. The outputs are direct driven from hybrid stick TDA type solid state amp chips.
The power transformet is probably about 100 watt size and supplies two voltages... one that feeds a +/- 15 volt three terminal regulators... Probably 22 volts +/- to the regualtors and the other supply will be unregulated to the power amp chips.
I recently bought the same bike and had the same problem. I contacted Diamondback and they told me that power adapter fits several models. The basic specs are 120V, 60 Hz input and 9VDC 1 amp output. The OD for the plug is 5.5mm and you should be able to find these plugs/transformers at Radioshack
Any power supply will do as long as it has the same specs as the dead one, which will be:
Input : x Volts AC
Output: x Volts AC or DC
Watts: x
Amps: in millamps
Polarity: (for power supply with DC output only) Center pin = plus or Center pin = minus
You should be able to find the matching transformer/adapter/power supply at Radio Shack.
More info, let me know.

P.S. The power supply you received may be the correct one -- check to see if the specs match the old one.
If you are refering to the DC +- 65 Volts the AC side will be different. What you need to find out is the average loaded AC volts on the secondary side of the transformer.
Below is the link to one of the biggest transformer companies in the world. I go to them all the time for transformers and power supplies for high end audio equipment and especialy for custom design and construction. I am sure they can wind you a new transformer once they know the exact specs you need.
