Ebay HI-END TA2024 DIY KIT,ASSEMBLED MODULE, anybody tried it?
 
Has anybody tried this?

http://cgi.ebay.co.uk/T-AMP-Digital-...QQcmdZViewItem

I tried a search, but couldn't find anything. Maybe I had the wrong argument.

I always liked surface mount myself, this looks like a nicely done board. Looks like electrolytics on the input tho'

Clever gimmick. :D

What I don't like:
Shonky shipping fees. (though it is international shipping..)
Bipolar electrolytics in the input (easily changed, there's some space for bigger caps but nothing really large)
Power supply filter caps look too small.
Ferrite cored indultors.
tripath chip's heatsinks not soldered to the board.
DC power socket, what's wrong with spade lugs or screw terminals?
is it a fake chip?

What I do like:
High quality, compact board.
Trimpot adjusted DC offset.
Soldering is MUCH better than all four Trends TA10.1 I've had.
Cheap!

I wish I'd seen these 4 months ago. I'd buy it and fix the things I listed and it's still cheaper than the Trends.

If you look at the pics, you can see that one pic has electrolytics at input, while the other has some box film caps. The shipping is pretty crazy for sure. The photo links to picasa also point to a different product. :whazzat:

That's the Tripath Evaluation board isn't it?

I bought one of those aready. UKP13 shipped.

Thanks for the feedback. The pricing and shipping are a bit weird, but it probably means less likelihood of trouble at customs, and you can just figure it as total price. I always figure the shipping in internet buys. The prices aren't consistent from item to item either.

As to the chip being a fake... seems a bit unlikely, the board has lots of other genuine looking components. I haven't been able to source the chip alone yet, but it can't cost much.

Can't tell whether the power supply is any good or just a junker. I've got some old but good 'D' nicads here, they are capable of putting out 20A+ no problem, I thought I might try running off 10 of those, the pack voltage is around 13.8 fully charged.

For Cubase I got a little 4-channel Behringer mixer that I run into an MAudio 2496 in my desktop (or a Behringer USB DAC on the laptop), I want something to run that into for listening instead of powered monitors.

I got some Audio Nirvana Super 8's coming. I'm going to build the 2.8cft box.

I might buy one of these anyway.

Looks like it has got Oscons on it. Weren't these supposed to be the dogs about 10 years ago.

Not a good idea, max voltage for the tripath chip is 13.2V according to the datasheet. You'll have to drop it with a couple of diodes.
