Mono-Block Pwr Test (first step)
Hi all,
initial steps are focused on the power output at various frequencies (continuous and burst). I think there is much curiosity about this very compact PSU.  Listening is very hard on percussion. PSU tested without fan (the maximum temperature was 65 ° (25 ° ambient) Short'll measures IMD and THD VS. Frequency. Regards |

here is another project
nothing really special ....just my old favourite pcb schematic and so on ...
usually i call these "relaxation projects " and i do this just to practice my skills on box artwork and how to make my amps look more pro the mask is actually very nice and also very cheap to make ....i have no idea how do they call this material its actually a simple paper that you can print anything you like and onatop they apply a special kind of resin that is good looking soft to drill and/or process virtually unscratchable and easy to attach costs 15 euro each no matter how many pcs you will print ... the metal work was done in a metal shop that supply metal allready coated with colour ( plastic film ) that actually is quiet strong ,oil free , and it will stand the process of bending without scratches or loosing the colour ... regards sakis

Happy Easter Sakis & Kali Anastasi!
Nice front panel Sakis. And the parts arrangement inside it is very good. I suspect - from the orientation of heatsink - that you have the option to mount a blower on the side panel.
My best wishes for a Happy Easter to you and your family. My best wishes for a Happy Easter to all members which are Christians, AND ALL THE BEST TO THE REST MEMBERS which are no Christians. Fotios Last edited by fotios; 3rd April 2010 at 06:03 PM. |
