Ok so i was toying with an idea to build a power amp for my tritrix(8 ohms, under construction)
Requirements
a) Max possible ampification around 100Wpc.
b) should fit my budget which tops at around 10k
c) Should Fit my capability and limited ectronics knowledge.
For the purpose honed on to the MyRef posted by Linuxguru, shot him a mail regarding the availability of the kit he was procuring (he was prompt in responding, thanks).
Problem : The amps have a max power limitation of around 40watts.
Was researching on the application of the LM3886 in parallel and came across

This project uses it in a bridged configuration to achieve 300W @4ohms mono.
Possible solution to my problem: I guessed i could use the same as 150W@8ohms stereo without bridging.
To top it all there is a parallel LM3886 combination available @ Ebay
LM3886 3 x 159W Parallel Mono Channel Amplifier Board - eBay (item 270644493655 end time Nov-02-10 21:31:50 PDT)
On closer inspection the Ebay board is a clone of the BPA300 which i was looking at as a possible solution.
Help required
a) Views and recommendations on the ebay thing.
b) I guess i should just require a trafo, heatsinks n chassis more to complete the project.
c) Help of the senior members to evaluate this n give an advice on the workability.
