Sure Electronics 2x300W (TAS5630) & 2x250W (IRS2092)
 
Just saw these for sale on their Ebay store. Has anyone bought them?

Thinking of buying one of these to power my tapped horn. 50Watts just doesn't cut it anymore :p

Strangely enough, they do have "More than 10 available" near the Buy it Now button for the 2x300w. Seems that the 2x250w is available for sale too :p

I would be very careful about them. It looks like they designed new models, but a while ago i read this post on the TI e2e forum. Look at the files he included. The name on the schematic tells that it is from sure electronics. The routing is quite messy and the inductors they used(they changed them in the new module) were not up to standard.

I don't know if they improved it in the new design(and this is the 1x600W), but if the designer is the same, i would be careful about trusting the boards :)

I was going to buy the TAS5630 board, but SURE still have to work bugs out of their technology, IMO (see my post at http://www.diyaudio.com/forums/class...8-example.html ).

Are there any low-cost alternatives out there? I could only find Sinewave Electronics, who wouldn't sell me just one board:

Buy 4CHANNEL, 4x300W, TAS5630, 4CHANNEL 1200W DUAL TAS5630 High Field CLASS D Amp at Aliexpress.com

Wholesale TAS5630 AND SMPS AII IN ONE BOARD

..trevor..

I know you don't like the company, but Welcome to CAD AUDIO DK have several sinewave modules and sold as 1 pcs.

Thanks for the tip, Kjeldsen :)

I personally have no opinion with respect to CADaudio, never bought from them. The prices look good, though, especially for members who live in Europe :)

The company have been around for many years, and I have bought from them without trouble. But some members (or at least one) have had some problems with getting a refund for a delivery that was not shipped.

also class d audio have 5630 based amps, but they don't come cheap though

@petemateYeah true. I do own one of their TK2050 4x100W boards and it has been working flawlessly. However there had been cases where their earlier boards tend to "die". Might be better to wait a bit first :)

@Kjeldsen CadAudio seems to have some pretty nice boards for sale. However shipping down to Australia is gonna cost quite a bit though.
