Default Pics of my new 4 Channel AMP

The following are Pics of my current Amp. The Amp has 4 channels for my Biamped speakers that I am building. I dont think may DIY's are using the method of construction that I have used here. The front amd back panels are held together by 4 square section AL rods which have been drilled and taped... I have used this method of case building for quite a few amps.

A unique feature (that I copied ) is that the amp's on-off switch is a Key. I originally thought that it would be a good idea to stop my kids messing with the setup when i wasnt around ( they dont, so the key has never left the hole)

What do you think ?

Looks awesome. May I ask where you buy the parts to make the case? I am looking into building one as well.

mFinalHeaven:
the case is made from AL that I purchase from a AL reseller. I just ordered the AL cut to my specs - this includes the square bar. To do the rest you need a Drill bench press. After I drilled and tapped the four bars and drilled the panels, I use Steel wool to take out any scratches. The final stage is finding a company that anodises the AL. I hope this helps!!!!

Vivek:
there is only one answer to that question - Fantastic. On a serious note the Amp has plenty of VA in reserve. I like to build amps with over speced power supplies - to me the always sound better. The Amp has 800VA power and Audio output @ 8ohms is approx 70wrms X 4.

Hi Lisandro_P

The Operation of the Power switch and LEDS may not be obvious. The Middle LED indicated Mains Power is on. The Left and Right Leds are connected across the 2 rails. As long as Ive built Power amps, ive always had 2 leds for power - I dont really know why.... The power Key only has 12V to it. Their is a small transformer which supplies 12 all the time and when the the is activated, a 20A relay applies power to the main Transformers - Im curious to find out if anyone else has used this method for Power On.

The Chrome plates that say "power" and "standby" were purchased from a Trophy Shop. 15 years ago i would have used rub on letters, but i cant seem to buy these any more. Is this other peoples experience or are they just not available in AUS?

BTW the extra holes in the back of the amp are from an amp which i started 15 years ago and never finished.. so I just recycled the case.
