Cary 306/200 service?

I have a Cary 306/200 with a sticky drawer that won't close all the way and opens back up. Works a little better if eveything's warmer (our house can be chilly in the winter). Cary no longer services these and I'd love to get it fixed. Otherwise, it works fine and sounds great. I live about 100 miles north of NYC....nestled in the scenic Hudson Valley...
Thanks for your help!
