Kaiser Radio

[sidbartos]

Hey guys, Im usually over on the audiokarma boards reading about vintage pioneer equipment but a new piece of equipment brings me over here. Last weekend I was going browsing through the craigslist electronics section while my girlfriend was here and came across an old Kaiser AM/FM/SW tabletop radio for $40. I decided not to act on it being a poor college student and all and forgot about it. Well sunday night by girlfriend comes over with a surprise in the trunk of her car..she went and picked up the radio for me knowing it was hard for me to pass up. It looks to be in amazing condition for its age and functions quite well...but I come with a few questions: First, I can't seem to find any model information on the unit at all..I've just been able to get the manufacturing date of 1961 off of the inside from the main speaker, and any wording on the unit is in german, but no model information. Secondly, it has 2 problems,
1.) the switches are quite finicky and I really have to play with them to get it to stay on a certain band so I was wondering how I could clean those.
2.) The radio has 3 speakers but only the front speaker works, not the 2 sides so Im not quite sure how to diagnose the problem.
The inside of the unit is absolutely caked in 50 years of dust so I definitely have to clean it up. I've done some technical stuff with my more "modern" pioneer receiver but I have no idea how to deal with tube equipment..it's a whole different ball game to me. Any advice would be great!
