My Sure based IRS2092 amp would work for about an hour. Then the right channel would cut out, the volume would lower and a loud hum would commence. I had read on another 2092 thread that Sure doesn't seem to adjust these at the factory, so that's probably why mine would heat up mercilessly too. Way too hot for Class D I thought - and I had it in a well-vented enclosure. I'm just going to cut my loses and probably not by Sure anymore. There are other, better modules out there. I haven't received the new 2092 module from Cristi yet at Connexelectronic, but his SMPS modules and speaker protection boards are first rate. I'm sure I can expect the same from him with this amp.
My next project will be based on this module.

Hi Rod,
Actually, this is the TK2050 module from HiFimeDIY I have. It's been on my bench, wired up and tested, but hasn't found a permanent enclosure, or home yet. Thinking about making a little iPod amp for my daughter with it. Can't beat the price.See attached image below.

Thanks Rick. Actually I have his T4 amp sitting and not built up yet. When I finally go active on our 3 front 104 db efficient speakers I'm going to need more amps. So trying to get a feel for which way to go.
Cheers,
Rod
Great info, thanks.
Hi,
with a cordless screwdriver you can easily twist the pairs.
Keeping the wires under tension while twisting makes them become straight.
Then it's just a matter of cutting and bending with some long nosed pliers.
For sure some ambition and patience is also required.

Since it's in my HT, the SC-05 probably gets more use - at least for movies.Hmm, sounds like the SC-05 is more favorite than the IRS2092
But even for 2-channel it is very sweet sounding indeed. I'm sure it's not the ICEPower modules alone that works the magic, but other things Pioneer has done on the inside to optimize the sound as well. When I haven't fired up my vintage rig, the LJM amp is the one normally on for general CD listening.Rick
Yeah they have some interesting audio stuff on that site. DACs, digital-amp(DDX320), and other neat stuff. Now you've got me curious about the T4. Powerful little module. I like the fact that it can take both dual, or single voltages. What PSU are you going to use with it? A conventional, dual-polarity linear one, or single SMPS? My credit card suffers when I start looking!

Hi Rick,
I got the Connexelectronic.com smps300R supply Connexelectronic The amp is really over powered for my Klipsch Heritage stuff but it's the one that HiFiMeDIY suggested for my speakers. My only concern with such high efficiency speakers is the amps noise level. Sure hope it's not a problem. Will probably be awhile before I do the build.
Yea those credit cards are dangerous little things!
Cheers,
Rod
This is my own version of IRS900, enjoy, it's working perfectly!

Foam Core Amplifier - TPA3118D2
Here is the new TI Class-D TPA3118D2 chip implemented in all SMD parts using dead bug point-to-point wiring with the components glued to a piece of foam core board. The amp sounds really nice and clean. The build was a lot of fun and I am not experiencing any noise issues that some thought may arise since I did not use a PCB with a ground plane. Although I do have a sheet of aluminum foil underneath the paper.

My TAS5630B Amp
Hello! Here're some pictures of my Tas5630b Class D Amp (the first one I designed). It works really great, I love this amp module.
Power is about 170W @ 4 Ohms each Channel. Heatsink is a Pentium 4 Socket 423.
Inductors are Coilcraft VER2923 with 6,8µH. I will try 10µH also.
Btw: If someone is interessted in a pcb, contact me ;-)
Best regards,
Bernhard
