Greetings loopas: I am looking for the service manual for a Multivox MX-312 Multi-Echo. Mine has some mechanical problems (drive shaft for the tape loop only turns periodically, and even with a little boost, eventually slows down to a stop), and I'd like to see if the docs can help me out with this problem. Let me know if you have it and we can work something out. Jason P.S. I have the owner's manual and tape changing instructions for the Multi-Echo. If anyone needs them, let me know I can make copies.
