I found an other little project. This “walkman” is a mono cassette-recorder/player. It has 1 knob recording, adjustable bandspeed and a speaker. I think it was more a dictaphone then walkman.
It still looks like new but needs some TLC. I still have a bunch of cassettes I taped in the 80’s from the radio. Would be fun to be able to use them again.
First step: information gathering. There is not much info available so I first have to find out how to open it the best way. Then how to clean and lubricate it. Check belts and rubber parts. Adjusting it will be not possible because I do not have the special tapes needed. So if it sounds not right I will try to set the azimuth by ear using the tapes I have. Speed is not needed and it is only mono.
Opening is easy, all is screwed instead of the modern way with plastic tabs that often break. But the PCB has a lot of wires you need to de-solder. And locate them before you do anything because they only have 5 strands and already break if you look a bit angry towards them. The pcb has no marking so you need to make a lot of pictures and drawings before de-soldering.
The left top is for the sandcolor, the right one for the black wire.
To the motor.
After this the mechanism is visible. I did not dare to take it further apart without a manual but it was enough to clean and lubricate things. The belts looked still well and did not slip. But there is a problem. I found this sticking to the metal. I’m pretty sure this is supposed to be mounted to something.
To be continued, i hope 🙂
Update, he works but the sound quality is not great. I think it is filtered for voice recording.
