For those of you early-adapters who are also retro-modders, you will want to hack a 50s radio with MP3 player and FM radio so you can enjoy music with the old vacuum tubes.
The idea is that the mp3 player and the FM receiver’s audio signals are re-modulated by using an AM modulator to keep the sound quality as it was. The radio now has IR remote that is actually from a car mp3 player (see the last image). The radio receives FM stations from a tuner PCB taken out from a working FM radio receiver.
Now thanks to Edo, once again this radio plays favorite tunes through the good old warm sound of vacuum tubes.
