Hello everyone.I've decided to buy PCB's for my gainclone project. I've found a great deal in eBay, but there is no manual or schematic for the PCB. LM3886 Power Amplifier PCB for DIY NEW | eBay Here you can see the offer. Maybe some of you have built this and have at least schematic?
If you now decide you need a manual and/or tech data (but don't know where to find it.....), and the vendor didn't supply it--was the purchase of these PCBs really such a good deal? (Deep philosophical question, here....)
Try the Chipamp.com website. I'm certain your final design will be close to the info Brian provides in his data. This should give you enough info to use--and take a look at the LM3886 chip manufacture's tech data, as well.
Good luck......

Ive bought these PCB"s and they are just Fine ..... The Schematic they give you with the PCB doesn"t exactly match the PCB but it is fairly close , the Schematic they give you is basicly just a copy of the Datasheet Schematic ..... The PSU PCB doesn"t come with a schematic .....
The Supply Bypass caps on the PCB are really small (100uF) and there isn"t really a lot of room to add bigger caps .......
Cheers
