There are two Yahoo groups I know of, Search for "Wwrlitzer and Seeburg". Seeburg requires admin approval, I've been waiting for a month. Very knowledgeable and friendly people i've found in the Wurlitzer group, and yes they are juke junkies, so don't let their name scare you off.
I have to second Dave's opinion of the jukebox list,, knowledgeable, but gosh forbid if you don't word you're question correctly, and golly, it's 2008, look into some forum software already. I end up using google to search their archives, there is no master index or search function, your other option is opening each month's archive , tedious.
The DS160 is a cool machine, and going up in value, so hold on to that puppy. It was one of the last models Seeburg madw with the exposed record mech. Do you have the ear speakers? If you find them cheap, grab them. They are going for $200-$300 a pair
Sorry, Jukes are my second passion next to soda machines, and I am working with a friend to rpeop parts not available.
Some of my favorite Vendors:
http://www.jukeboxfridaynight.com/ - Bill Vickers has prolly forgot more than I've learned about Jukes. The man to go to for cap and tube kits.
Victoryglass.com - The Funtronics of jukebox parts. Have a question, give Denny a call.
http://www.jukeboxusa.com - another place for parts.
http://www.coinopwarehouse.com - lloyd bought the remaining inventory of Wurco, a good source for used parts.
The manuals for the 160 are available from Victory and JukeboxUSA, high quality, not a zerox print that often show up on Ebay. There are also several shops in the Netherlands, Germany and the UK,
My suggestion, holds on to to your 160 for a while, the early 60's Seeburgs are starting to rise in value, much like the squaretops.
