Hi, Selling my AMP 3 module for the DX200 as I'm selling all my gear and sold the DX200 separately. It's a 2.5mm balanced-only module. Reviews on this module speak for themselves, I'll just say I didn't go back to AMP 1 after receiving this. Perfect working condition, screws show sign of use as I tested the two AMPs back and forth at first, but no functional issues and no scratches on the module itself as I never used the DX200 without the case. I lost the original screwdriver that came with the module but am including another one of the same tip size that works perfectly with it. $125 includes PayPal and domestic (US) shipping. International shipping available at extra cost to the buyer.
