I got it working!
Next, I'm building the real thing with Brian's boards and good parts. Things that I did wrong in this project: 1. Short between one of the pins of the LM chip and the ground. 2. I may have wired the first caps wrong (Not sure about this). 3. Didn't use Mica to isolate the LM chips and the heat sink (the heat sinks were not connected to ground and didn't seem to matter). 4. I wired the bridges wrong ( I had used a single bridge per channel instead of combining them for the + and - power). It sounds pretty good, considering the cheapo parts. I'll compare it with the good amp once it's built. Thank you all for your help. Jam |
