For some reason, I am hard on Lionel CAB-2 remotes. I've been through several, and apparently the only way to get a new one is to purchase a full #990 or #993 set.
My main problem is that some keys on the CAB-2 become sticky and refuse to make contact. Also, the red velocity knob tends to freeze. Is there some type of lubricant to apply to the keys and/or velocity knob to free them? I have tried Deoxit spray, which has only temporary (or no) effect.
