Perfect solution to my technical problem

I have a so-called "vintage receiver" from Grundig. At the same time, a tablet with Bluetooth receiver / transmitter. On my tablet are MP3 files that I wanted to hear about my existing stereo. The replace my vintage receiver did not come here in question. The adapter Philips solves the problem perfectly. Simply plugged back of my vintage receiver to the RCA cables, and you can be my Receiver Bluetooth receiver. No problems with reception, no Clitches, no cable for Tablet. Excellent.
