What to do about GFA-2535 damaged in shipping?
Yesterday I received an Adcom GFA-2535 that I won on eBay. The seller charged $40 for shipping on top of a ~$120 sale price, and I foolishly thought that that would include proper packing. Instead, the unit was packed in crumpled newspaper, inside a single re-used flimsy cardboard box, and shipped USPS for $20. Unsurprisingly, one set of speaker binding posts are severely damaged (bent over, plastic cracked, sheet metal on back of amp distorted).
I'm expecting that the seller will claim it's not their fault and I'll never get any compensation. I'm hoping, though, that since my other Adcom vintage gear is all built like tanks I can open up the case, remove the damaged posts, bend the sheet metal back into flatness, and install replacement binding posts.
Anyone have any advice about do's, don'ts, or other recommendations on how to proceed? Think it's worth asking the seller to reimburse me some portion of the sale cost since I ended up with damaged goods?
