10-May-2010: Finally got round to desoldering the IRFP250 MOSFETs and dropping the IGBTs into my 160W n-channel MOSFET power amp as a quick test to see how they fared in a known design. Initial results seem promising, listening to it in the background right now!
13-May-2010: The IGBTs are doing so well that I've started redesigning the PCB, making it more compact and upgrading some of the components. It's definitely a lot more than a sub amp.
30-May-2010: Added my component library for Sprint-Layout PCB software to the Utilities section.
Plan for the coming weeks is to convert the PDF info into normal web pages, speaker testing guide has now been converted.
The PCB milling machine project will be delayed whilst my garage is converted, ETA September. This will allow me to start selling boards made to order with quick turnaround and at a low price. I am also considering making boards to customer supplied layouts and small parts such as front and rear panels.
