Default TOP201YAI 3-Terminal TO-220 PWM switch Figure #7 in date sheet

I would like to know what the specifications for the transformer in this data sheet is I would like to build one
Also for figure number 8 as well
Also for figure number 9 as well

Here is the data sheet I know that this item has been disconnected but I can buy them surplus

I have a mad scientist streak in me lately and want to be a little adventurous

The reason is I have some ATX switching power supply that I have as spare parts from and wondering if I could use one for this purpose

Or just use the standby circuit that is for this purpose but then I would have to reengineer the circuit to be able to use just this part of it
9 PC LCD Monitor
6 LCD Flat Screen TV
30 Desk Top Switching Power Supply
10 Battery Charger Switching Power Supply for Power Tool
6 18v Lithium Battery Power Boards for Tool Battery Packs
1 XBox 360 Switching Power Supply and M Board
25 Servo Drives 220/460 3 Phase
6 De-soldering Station Switching Power Supply 1 Power Supply
1 Dell Mother Board
15 Computer Power Supply
1 HP Printer Supply & Control Board * lighting finished it *

These two repairs where found with a ESR meter...> Temp at 50*F then at 90*F the ESR reading more than 10%

1 Over Head Crane Current Sensing Board ( VFD Failure Five Years Later )
2 Hem Saw Computer Stack Board

All of these had CAPs POOF
All of the mosfet that are taken out by bad caps
