Yep, that's the post I used. Pretty easy to do, just work slowly and be sure not do drop any small parts. Some tips from a guy who just did this-

The stock lamps are of 3 different sizes. I replaced them with 3 of the same size from Radio Shack. I bought the smallest 12V lamps they had in stock. They're very small, clear glass, but very bright. I would recommend leaving the colored green slip on jacket on the lamp that goes in the volume/tone bezel. I left mine off, and it's almost too bright. I'd leave them off the other 2 lamps for the dispaly & buttons - nice bright display - but that's personal taste I guess.

If you can find replacement lamps of the exact same size as the originals, it's best. There are little rubber grommets that fix them in place (so the light goes where it should), and while they will work for smaller lamps, the same size is a better fit. Also, the colored sleeves will fit better.

The new lamps I found did not have insulated wires - they had uninsulated 1.5" fixed leads. Buy some very small shrink wrap you can use as insulation. Otherwise you could use tape, but that's crummy.

If you need the room to work, or access to the wires, the entire "tape" section is easily removed with a couple of screws. There are 2 modular wire connectors also. Just remove the tape section, and you can more easily get some slack on the wires if you need it (I had to since my wires were hard & un-strippable near the ends).
