Can u tell me whether I can add bt in that AMP IN slot with separate 5v power from battery. Just wanna try whether it works or not...
And if dosen't work which 2.1 amplifier ic bord i can use for around 100 w total power output.
True... Mfg year on transformer is 1993....i was curious if i can add bluetooth modul in this and attach in 1 speaker for personal use. But m scared as it ll run on power supply that was powering whole music system which is also 30 y o.Certainly there were bass speakers, but the subwoofer for that thumping bass was not part of most music systems at the time. My Marantz system has 8 inch woofers, and produced very nice rock, back in 1985. But there were no sub-base sounds.
That came mostly with the "RAP" sound, which I do not put in the same realm as any actual music.
TDA 1521, 23807, HSH9210 4 I am guessing that the HSH is the plant code for the IC, 92 is the year,10 is for October, and 4 is the day. Most larger semiconductor devices do have a date code that is for quality control purposes. This is my interpretation. That would have the amp being close to30years old, since all of the parts would be a bit older than the assembly.
