Very nice mrsbadcrumble!

I like the idea of using a cast aluminum enclosure with a thick front panel.

Cheers!

It's nice job mrsbadcrumble

you portioned power section from amp section,It's beneficial to prevent magnetic obstacles.

You'ýý can add capacitor to power board except others,which are on the amp board

Finally
your amp is being seen very nice

I loaded Vista, went back to XP. I loaded Microsoft 7 beta, went back to XP... I know, I know, "it's Linux time" <wonder if MC Hammer is going to patent that one>..
Nice tip! That will come in quite handy. I've used Visualizer Photo Resize up until now.

Anyway...back to the photos!

I found sourcing the mechanical parts took a long time but was quite good fun. Some of the contributors to this forum have excellent websites and they put a lot of detailed about the electronics but forget the ‘nuts n bolts’ aspect leaving you with no option but to search the web.
Unfortunately the web is a word based search engine (at least as far as I know!) and you need to know the name of the ‘thing’ you are seeking. You should also be aware that identical products will have different names in different industries, and that’s before you take into account different countries!

The extension bars are made up from a Brass Coupler Ľ” and 6mm aluminium rod cut to length. What isn’t seen in the photo is that each extension bar passes through 6mm diameter bushes held in the front plate.

Brass Coupler - Made by Jackson Bros in the UK but I got them via ebay.co.uk from a seller called Mainline Electronics Ltd. They say they post worldwide...

Good Luck

Jeff

Very nice ryan750! Do you really need those fun?. I ask you this question , because you can avoid any noises from fun just eliminatering them. in my case I do not use fun, instead I use a proper size heat sink (BIG) and it never gets hot and it is quiet as a mouse!

@ryan750

chief ryan ok yan

@lanchile

May i ask you sir what's your room temperature at your hometown. thanks

One reason why ryan use fan, is because we could not find a better heatsink here unless ordered it online which will be better to buy a OLD model kenwood av receiver here, because of the price and the tax. 2nd is the room temperature, actually the one i posted uses smaller heatsink to what ryan posted but the same type "because i need the lm4780 to be compact. The circuit actually good when our room temp is at 29c below, but when it return to normal 32c up, you cannot use it at higher volume without the fan .

Anyway so much for that
Before i plan to buy a good case from china but because of tax here, i decided to buy a 2004 model kenwood av receiver which is more powerful and better in terms of sound quality.

Anyway more power to all chipamp users
