Bonsai,
That looks really impressive. Why do you tempt us so?Are you planning on offering this as PCBs only, full kit, enclosure, etc? Or, a commercial product through hifisonix.com?

No I am not going to offer them for sale. I will just put the Gerbers and BOM up when the design is fully debugged and tested.
Thanks Fotios - any new designs/constructions from your side? Hope things are going ok in your home country.
Yes, you can experiment with opamps in this design as long as they are single channel DIP.
Here's my not so nice looking 150+150W @4 ohms, 2 yr. old integrated amp. but, of course very nice sounding . It's a very simple design, PCB is taken from a 50+50W, 2N3055 amp kit, with some changes to accommodate the upgraded circuit. also there's a 5 band equalizer on it's top.

Aniket

not look nice? dude that is a beauty do not mind about that you are a pioneer like us searching and designing audio amplifier I call that "audio art" (Audison)

Swetone Phono
This is a project I just finished for someone else. It's a simple phono pre based on the LT1115. The box is from Par-Metal. One thing we did which I've never seen before is to use a trophy shop to make the front and rear artwork & lettering. It was a little tricky drilling through both, but I managed OK. He picked out the design for the panels. Total cost was about $250. I felt honored to be asked to make something for someone else. It's the first time for me. I hope he likes it.

Hi guys, this is still a work in progress.
Its a 5.1 amp system, 5 LM3875T modules for my satellite speakers, and a 250 watt class D module for the subwoofer.
The entire system will soon be controller with an arduino to control speaker protecting, and power saving.
Ampduino!
Ignore that little module in the middle cable tied to the speaker lines, its a temporary 12 volt PSU to get it running for testing.
I still have to mount the power control system, soft start, speaker protection system, and on/off switch.
Oh and snubber caps on the rectifier bridges.

An externally hosted image should be here but it was not working when we last tested it.

Yup, dont use AC wiring colours for your DC stuff, especially dont make Earth anything other then earth.
Other then that a nice layout.
Noted; I'll make sure my next amp is wired with the correct colours. Thanks for the info.
