If this mkII mod was performed by Rich, Wayne, Greg, or me then you are golden. Obviously we cannot warranty shipping damage. But if the amp fails we will make it right. Speaking for myself.
I am not this guy: I have no since of humor.
And I am certainly not this guy: Please
But if you have any problems with your amp then I am this guy: I will do any warranty work required since this is a RichP modified amplifier.
Please let us know the eBay sellers handle so we can protect ourselves from him.
Time to file a claim with eBay. I would take this as far as you can. Please don't let him get away with it. Did you take pictures of the packing?
A member here bought four M-500t's on eBay. He had the seller send two of them directly to me for mods. Both were packed together in one box. He used crumpled news paper for filler. Nothing else. Surprise! Fortunately their was only minor damage. I was able to repair the plastic meter face plate pieces with JB Weld.
Welcome friend!
That breaks my heart to see that.
Unfortunately finding a new face plate and plastic trim will be difficult. I am not aware of any M-500t parts donors between the technicians here. Have you made an attempt to contact the seller? Or begin the eBay claim process?
