only thing is mine doesnt say mac 500 it has the 2125 end caps but I do have original birth sheet so it is real just may have been a earlier one or later, wish someone knew something about these, I' m not sure how many they produced? would love to know though possibly one of the least seen ones ever that were produced for sale to public

You sure? IIRC the MAC amps were specifically designed and sold for the european market.
actually these amps still put out more power into 2 ohm stereo 4 ohm mono a local shop near me sold a half dozen of these around here back in the day I can,t wait till some locals start clearing out there closets didn,t know how lucky I was to get one of these, mind you it wasn,t cheap heres a couple pics of the paperwork with the specs
We have been down this road before. The MAC500 is a MS2250TA.
Open it up and study the parts, they are the same amps. If the MAC500 were optimized for an 8 ohm load it would have more output voltage than an original MS2250, and it does not.
I am just guessing at the history of this, but I think PG came up with the MAC500 as a reduced output MS2250, since a lot of MS2250s probably failed. Their design runs the parts near their limitations. They cut the output voltage and named it a MAC500. Then years later when PG got the idea for the MS amps tenth anniversary come back, they chose the MAC500 as it was a lot more reliable, but still had more output than the MS2125.
So the only thing that makes this amp special is the silk screening of the MAC500 name on the end. If someone made a few of these and put them on MS2250TAs, they would have the same amp.
Got "schooled" by member shawn k on May 10th, 2011...
No longer really "in tune" with the audio industry, and probably have not been for some time.
Hands down the forum's most ignorant member...
Don't even know what Ohm's law is...

Wow...
I did not catch this earlier.
I appreciate your input here Eric, it sure does.
Anyways, I would very much appreciate to have some of those MACs for collecting reasons...
