Ok, that's what we want to know: That you have a full AC input to the power transformer.
Next, we're going to check the output of the transformer. Keep your meter on AC volts. This time, however, we're going back to that same set of wire wrapped points in the middle of the board.
In the snip below, I've highlighted the 2 red and 1 black wire that comes from the transformer and are wire wrapped to the board. I've circled the 3 wires that we're interested in.
What you're going to do is to take your black lead and connect it to the black wire wrapped terminal. Then, you'll take the red lead and measure each of the red wire wrapped terminals individually. There better be an AC voltage there and it should be roughly the same for both of the red wires.

Unfortunately, I'll out of town the rest of the week and will not be available until the middle of next week. Perhaps one of the other 'arm chair bench techs' around here can pick it up.
To that crowd:
- The OP reports he's got no power to anything on the TT but it did at one time.
- I've had him check the DC output of the regulating transistor and he's confirmed there no voltage there. That would be the red wire-wrapped terminal in the middle of the PS board.
- He has confirmed that there's 120 volts getting to the power transformer.
- Now we need to confirm there's AC getting out of it (suspect so).
Good luck!
Cheers,
