Monster Amp MPA3250

Hi .. has anyone been able to squeeze a service manual of some sort out of Monster Electronics for the MPA2250 or MPA3250 .. I've talked to them a year ago or so and they insisted there was none available. The tech I talked to said ypu have to send the amp in. OK 93 lb AMP shipping charges to and from.
Maybe if enough people bugged them they would release one. These products are out of production now.
