Its OK to sub in for testing but the 105 needs to go in eventually.
Most new 'lytics come in the following.
1mfd, 2.2, 3.3, 4.7, 10, 22, 33, 47, 100mfd etc
Sub a little over the mfd if need be. The new caps wont be cans.
Pick up some terminal strips to mount them & be sure to cut out
the old cans, not leaving them in circuit.

Yes there's one single value can mounted on an insulator in the TV its a 140 MFD 150 VDC capacitor.

The rest of the capacitors are mounted straight to the chassis. So what is it about the voltage doubler circuit that it needs to have a high temp. rated capacitor in that spot?
