Hi guys, I have a question about TDA chip in Vupyr-15 power amp section:
http://music-electronics-forum.com/attachments/5037d1239065731-pv-vypyr-15-pa.pdf
What is the purpose of the current sense circuit in the speaker feedback loop? I read somewhere that it's there to raise amp's output impedance to mimic tube amps; is that true? and how does it affect the sound?
Another question is how does it affect the amp's gain?
Thanks
Sajad
