Hi Rebecca, sorry for the delay, I didn't see that you'd edited your last post but now after looking at the pictures I believe I can hazard a guess on your problem. In the center bottom of your machine is a single head. It's the squared off metal "can" with the wires coming out of the top(has the model number printed on it). Just to the right of that is the capstan. It is the rod with a brass washer on it. Just below that is another rod sticking out. It has a hole in the end and a reddish washer on it. That hole is where a screw that secures a rubber pinch roller should be. both are missing. You may be able to have one made if someone has the specs of that part but that is doubtful. Your only other option would be to send the entire machine to someone to have one custom built and fitted. I'm not sure if this machine has some personal value for you, but either alternative still wouldn't assure that the machine would work. Most of these types of portables have very little resale value. They were pretty popular in the '60s and just about every home electronics company made one or two. My parents bought one each for my sister (a decent little Sony) and myself (a really awful little Aiwa since they knew I'd take it apart and destroy it in a matter of days) and we used to record stuff off the radio or TV (with the microphone taped to the speaker). Those little mono recorders seemed like magic at the time.
