The voltages in this project are potentially lethal! Proceed at your own risk!
Since I didn't want to risk frying my headphones and classic speakers, I installed 2500uf @ 16V electrolytic blocking capacitors at each channel’s output. Then, I bypassed the electrolytic caps with hermetically sealed 4uf paper caps just like I did to the Nobsound NS02g.
|Top trace = audio generator |
Bottom trace = amp output
In spite of the DC blocking caps at the output, the square waves still show excellent bandwidth, transient response with no trace of ringing.
BTW, did I mention that it can also drive my Altec 755As in Silbatone cabinets?
