amp stand on wheels

Maybe a used Billy Bags.

Note that these are available with casters, making them easy to move around. I had a friend who had two of these holding Audio Research REF 600 MK 3's and the effect was absolutely beautiful.

They are expensive but I think a great match for your MC 2500 amps.

I believe that Sound Anchors offers casters as an option on their amp stands.

I have,and will NEVER move away from,the Sound Anchors stand,w/casters.What a pleasure to actually access an amp(rarely done,but when it is,you appreciate the moveability).I have a Rowland 8t with additional chassis/power supply.Before updating chassis #2 it weighed 165lbs.Having to wait for my son,to come home from college,to re-pack the amp for updating was no fun!Best of luck.I believe I paid 175 each,some yrs back.They are also variable,with a sliding bar to accomodate most amp sizes.Good luck!

billy bags has one with castors on their blow out page.

Looks like just what you need.
