Please find some pics of my new amplifier, this works a dream with no issues at all. To my ears sounds very good. What do you think, the tiger eyes light up blue and indicate the PSU is healthy. There are quite a few threads on this site indicating issues with this design, well this one works 100%

Nice

Where did you get the case?

jamesfeline · 8th February 2010, 09:47 PM

the case is a maplin 2u case, I had the feet made by a local engineering company. Then I made a ali chassis plate to go on the bottom of the case to mount all the electronics onto. This is something I was playing around with, jamesfeline (thats me) so the tiger I thought was a good label for my work. On my next design the tiger eyes will change colour when the amplifier gets hot.

regards

Cool... i did wonder about the case, the Maplin one has a perforated base usually...

Did you do the front plate yourself or did you have that made? If you had it made, who did it and how much ?
