This receiver concept started as a enhanced Renkforce MP-2000 amplifier of 2x 100 (claimed) amplifier.
However, i measured 45w in stereo RMS unclipped, and wanted to see how i can improve these values, and get lower thermals.
The solution started with a simple capacitor increase (2x4700UF 35V to 2x6800UF, 50V)
I wanted to apply a speaker protection circuit too in case something goes wrong, and add more inputs, swap out the heatsink for a better one, add a dsp with tft screen, radio antenna, ect, ect...
Simply speaking: i only wanted to keep the enclosure and amplifier board.
Realizing this would be very expensive, i simply decided to make my own receiver, this way i could add multiple channels and outputs.
why the name? simple: Yet Another 50 Watt Receiver (YA-50WR for short)
