Realistic STA-225
#2

Let's start with...the death caps.

If you look closely at the one on the right, you will see that the case is cracked. So it needs to be replaced.

I have freed one end of each of the old line-to-ground caps. I've also discovered that the mystery component hidden under the plastic sleeve is a 2.2 megohm resistor.

I replaced all three components and...

New X1/Y2 safety caps and a new 2.2 megohm resistor, hidden inside black heatshrink tubing.

Since I have done this, I have also removed the original power supply electrolytics and physically replaced them with new 8200 uF Nichicons (they are not yet wired into place underneath). The new caps are the same diameter as the old ones, but the new ones are about 1/3 as tall as the originals.

more to come tomorrow...
