It's not a 900e as there is no heatsink on the side with a big white high wattage resister. It's an MTC-9000 as the left hand side of the board is clear and there is a fan on top of the lopt. THe MTC 9000 does give a good picture, the board is nowhere near new, although it might have been recapped and the LOPT been replaced. The most common fault is the LOPT dying and taking a resistor with it which literally goes up in smoke...
Glad you know your monitors ;-) I had a MTC-900E sent to me by Alpha and that's what I got.... the swine lol.
