I confused myself - my question was actually about the lens-type lamp on my 99k! I am planning to make a quilt on it and the bulb is burned out. Sorry it ended up in the 128 thread! Sounds like I can get a threaded LED light for the 99k, though. Where is a good place to look? I checked Sew Classic and sewingpartsonline and didn't see a threaded LED on either of them, just the bayonet type.
No cleaning done as yet on the 128. I was overcome by exhaustion today, for no particular reason, and all I've done is nap and read!!
