Gainclone building thread based on BrianGT's boards

Just got my breadboard up and running. A couple of questions. I have no on-off switch and upon plugging the amp in I get a rather loud, abrupt noise from the speakers. This is not a "wump" but is sharper in sound. The amp sounds fine and is dead quiet following this. As it is breadboarded, I have no star ground but have connected the two channel grounds together. No input power ground is currently used. Is it the lack of ground causing this or do I look elsewhere? I was surprised to find after 6-7 hours of play that the chips where not even warm to the touch. What's up with that? Why the heatsink if they run this cool? Appreciate any insight.

I am thinking about put one/two blue led inside, and made the gap blue... It will looks cool/cold, but it will be annoying while I'm watching movies with leds off.....except those blue light from the amp
😕


You could just put a small toggle switch in series with the DC lines to the LED's so that you can turn them off when you want to watch a movie. Alternatively, you could have it switch between connecting directly to the LED's or passing through a series resistor to dim them to a more appropriate level.

hey thats pretty off topic. i was just answering a question, not trying to get insultes and/or flamed.

why would someone say "its just a pc in a rack case" and then point out their smaller but slower and noisier 🙂 machine which is also just a pc in a rack case?

I have an idea. lets talk about gainclone building!


p.s. karma that is quite the massive setup you have there! does it need its own power circuit?
