This is a hand drawn circuit diagram for an "early Dutch Radio JukeBox". It's a PLL FM transmitter that broadcasts on 104MHz, with stereo sound.
You'll need to have some good experience with building FM transmitters to tackle this circuit, because there are almost no details given, so there no instruction on circuit operation or how to troubleshoot.
Component values are given, with the main RF transistor being the MRF-237. It uses 3 oscillators for the main RF section - interesting!
Please let us know if you build this intriguing FM transmitter - we definitely want to know how it works.
