That's the 648, or to be picky about it, that model is the TCD648250 or TCD648250B (and I have no idea what the difference is), and it uses a supply that's unique to that model because of the extra 7.5 Volt output for the front panel display.
I'll know in a few days if I can fix the 648 I'm getting or if I'll be interested in parting it out.
Too bad you aren't in Raleigh or Philly, I could refer you to someone who could do the repair in either of those two places.
But you're in a big enough place you should be able to find a repair shop that can answer "yes" to the question of "Can you guys replace some Low ESR, 105 degree caps in a switch mode power supply at a decent price?"
I wouldn't pay more than $50, parts included.
I can get you a list of the caps on the board that the culprit or culprits will be among in a few days.
