I would place the output connections closer to the amps, away from the input.


Yeah, I was just being lazy and using the existing holes. If I get round to changing the phonos to prettier ones I may well move them over a bit.

For the time being you can print your pinkmouse icon and glue it on the frontplate...

Possibly, but I think it needs something bold to fit with the style of the rest of the amp. I might get the dremel out and have a practice and see what I can come up with.
 
Nice case.... very pretty...good proportion

And a perfect choice of colours..... wonderfull work.

Carlos

I tried to achieve "all in one" unit, so it may look little bit messy.
There is 4 x Symasym and 2 x pcb with capacitors and diode bridges.
By the back side you can see active crossover, PCU for crossover and soft start.
Active crossover is one motherboard with 5 slots for each channel and 5 cards, which are:
1. balanced input with high frequency filter, 2. switchable filter (q cut), 3. switchable filter (high pass - when subwoofer is used), 4. high pass 24dB/oct, 5. low pass 24dB/oct.

Sorry about problems with pictures, they are located on freehosting domain (you get what you pay 😉 ).
 
Hi Mike,
At some point I'll decide to put a couple "into production" and continue developing. Keeps my wife happy so I can do more. 😉

I had a simple goal for these when I started. To drive in-wall speakers and possibly computer speakers. So the 50W model will fit the bill well. Then I have three daughters who deserve a very good amplifier, 'cause I can. You can't buy a Marantz anymore for the money they used to sell for, therefore I'll build them a great amp.
