Re: 8PAKAMP & 12PAKAMP KIT BUILD THREAD

OK. Just a bit of clarification needed please. What wattage do I need for ballast resistors? Would 5w 1% work? Also, I previously used 4k7 ohm input resistors to set gain instead of 5k trim pot. It sounds like I still need to do that then connect the chip inputs as you have drawn to parallel three d...

Re: 8PAKAMP & 12PAKAMP KIT BUILD THREAD

Thanks Joe. I put scope on each output. All looks fine. Revamped/added heatsinking and added small fan. Working great now. Next project with remaining kit is to build a 2 channel amp if possible. Can you show me how to configure the Pakamp 12 for two channels please? I am guessing this is a bridged/...

Re: 8PAKAMP & 12PAKAMP KIT BUILD THREAD

I finally have completed the amp and all channels seem to be working properly. Sounds great! Noise floor seems to be completely silent. So far only running low power due to heat issue and the fact that current speakers are 4Ohm. My plan was to run 8Ohm speakers with this configuration. I am surprise...

Re: 8PAKAMP & 12PAKAMP KIT BUILD THREAD

Starting to populate the first board. I have noticed that there are two parts that I need to acquire, ZD1 and R16. Both are labeled FAN and are adjacent to the 3 pin header labeled preamp header. Could you please provide guidance on what parts to get. I have selected a 600Kva transformer with two 18...

Hi Guys/Gals, I just ordered 12PAKAMP Blue kits and am hoping someone might be willing to share pics of their own implementation. Especially with MiniDSP interface details. I have searched for the MiniDSP Shield referenced but could not find it. I am planning to configure the board for 6 bridged cha...
