Wurlitzer 2204 transfer motor problem

Went through every selection A1-26 then B1-26 then C1-26 all selected without a problem. Continue on with the D's and with only two odd selections detented one was A-? and one B-? don't remember the numbers off the top of my head. Went back through the D selections an 2nd time with no incident. Possibly oxidation on some contacts, possibly music magic again.
Thank you all for the help, not sure what contacts were the offenders and whether I should clean them with a deoxit spray, contact cleaner spray or just use it and it will correct itself with regular use.

Any ideas of how to clean the grill with out having to remove it and without damaging the speakers. Also what do you recommend to clean the felt like material that is on the platform that surrounds the record carousel?

Ron, I am not sure what the acronym "ES" stands for, but could you provide the full name so I will recognize it in future topics.

Ken, I will keep Electronic Resourcing in mind the next time I need parts. I have been trying to purchase a supply of caps in the common values, but have not gotten enough of a variety at this point. I would like to stop by your shop and say howdy when I'm in your area if you don't mind.

Thanks again everyone, Craig.

Hi Craig,
IMHO--iffin itsa workin'--don't fizzit !!!
"WurlTizers term", as per the Service Manual, for "Electrical Selector", more commonly called "pinbank", in other brand, coin op. phono's Ron Rich

Thanks Ron.
I took a quick look for a glossary of terms in a wurlitzer manual (I had not looked for one in the past so was not sure if they had one) but did not find one, figured it was easier to ask you instead of digging through a manual to come across it by accident. I have gotten into the bad habit of calling them all pinbanks.....shame on me.
Thanks again, Craig.

Craig,
Tell whomever you prefer, that you need 50 lashes with a wet noodle, for that ( actually most everyone I know, in this biz call it a "Pinbank" too--except the guy who wrote the Manual--but "ES" is easier to type, for a lazy guy, such as me !). Ron Rich
