I don't know if anyone has noticed the Monolithic PA2400 on ebay item #280318088284. The description says refurbished, but that amp needs to go back to Greg and have some work done (only two rca's). I also believe this amp is an f series not the x that has the x-over built in. There are 0 bids with 19hrs left. It is also from Thailand, and I'm always skeptical about international orders. What do you guys think.
