What you need

Light Bulb
- Take off the back panel by unscrewing the 4 Phillips head screws on the back of the amplifier.
- Remove the four Phillips head screws on the top of the amp. These screws are significantly longer than the back panel screws.
- Remove the quarter inch speaker cable from the jack in the back of the amp.
- Unscrew the three remaining screws on the back side of the amp head as indicated by the green circles. Be sure to keep the amp secure as you do this because it will no longer be supported by any screws

You just did it the hard way. My light went out on my 65 Twin Reissue, and I just unscrewed the red jewel lens and pushed on the bulb slightly while rotating it coumterclockwise, and the bulb came right out. To replace it, I pushed the new bulb in and rotated it clockwise, screwed the jewel lens back on and it was done. This took 1 minute. Glad I could help.

I just replaced the pilot bulb on my Blues DeVille. I couldn’t get the new bulb to twist into the socket after I successfully removed the old bulb. I took the plastic cap from a small marker and cut a small slit so that it fit onto the top of the bulb nicely. I was able to push the bulb into the socket, twist it in, and then pull the marker top off of the bulb, leaving the pilot light securely in the socket.
