DIY Dual Mono Power Amps
Haven't posted for a while as I've been scouting around for my next project. I'm going to build a couple of mono power amps for use with my Beresford DAC.
The amps are based on the LM3886 chip amp. These chips are capable of delivering a very reasonable 68W. Each amp will have it's own dedicated power supply and be housed in a separate case.
The Chip Amp (or Gain Clone) is an extremely simple design, cheap to build and good for beginners such as me. Moreover, it's supposed to sound pretty good too.
I have already ordered the kit and it arrived today. The kit was purchased from ChipAmp.com and cost me £67. However, that only covers the cost of the PCBs and onboard components. Using the cost breakdown covered in my post on building the Novo, I expect the PCB and components to represent about half the cost of the completed project. However, as stated in that thread, the PSU supplied with the Novo was on the cheap side. So, allowing for two toroidal transformers, I expect that the total cost will probably be close to £200.
