Jeff,
My Tron #1562 has three outputs including the foot pedal. In the back, one is XLR and the other is 1/4 inch. These were machines sold by Sound Sales.
As for the knobs, mine came with the same shitty looking knobs you see in the photo. Streetly hooked me up with the proper ones. Mine still has the black and gold control panel faceplate, but for those that have one but don't like them, the black decal can be removed and the stock Mellotron faceplate is underneath.

PS. here is a photo. It is not me in the photo, though. This was when we were staging Anglagard for their NEARfest 03 performance.
