Dual 1219 speed control switch assembly

Has anyone opened one of the speed switch assemblies to clean and lubricate? Mine felt gummed up and I was sure NOT to force anything. Upon closer inspection I see dark amber colored / old hardened grease inside the clear plastic housing. Is disassembly best approach. Or is there some other way to free it up?

Hi, IMO it's best not to disassemble these speed controls unless you really know them well or want a huge headache trying to get it back together again. What I do is use some very long q tips soaked in alcohol and work that into and around the speed shift parts. I try to remove as much of the old grease as possible. Then using the q tips I work in fresh grease I like to use a grease called super lube in them. It seems to be able to loosen the parts up better then lithium grease does. As I work the fresh grease into the parts, I gently work the shift lever through the entire range of motion. Be very careful at first you don't want to break the the shift lever it self. I have done this successfully on a bunch of dual turntables. But on some I did have it take the shift lever a part becsuse the lever was stuck so bad. If you need to take it a part make sure you take a lot of pictures before you do so. If you can't get super lube then use a good quality lithium grease. I hope this helps and good luck.

I'm not at all familiar with these so I'll leave it be. I've taken pictures of the switch but this table is too nice for me to trust my skills on (which are very minimal) ha! I don't have very long q-tips but i have some pipe cleaners lying around which i could use to apply the iso-alcohol. I'll continue to gently work the switch when I do. This one is really gummed up as it has been sitting a long while. I am the second owner.
