I finally got the Wima capacitors from 8audio in Hong Kong. After soldering these to the TA2024 amplifier PCB (and adding a S$ 24 power adapter and some really old Aiwa speakers I got on ebay.com.sg) I now have sound!
The Tripath TA2024 is considered to be a very nice piece of audio gear, some people claim it's better than the GainClone (and all that for US $25 plus minimal shipping). And my DIY GainClone back in Manila sounds better than my Cambridge Audio amplifier, except for having a really ugly case, no volume control, and thumps on power-up and power-down.
I was really thinking of buying the Philips mini-component with a tube front-end, but it's gotten bad reviews and costs S$ 399 or thereabouts. Besides it's no secret that consumer electronic gear is as bad as the manufacturers can make it without pissing off customers. So for much less money (I did have to buy a power supply, soldering iron and a large roll of solder - they don't sell small quantities unlike at Alexan) I had half an hour of DIY fun and the knowledge that the amplifier I'm using is sonically superior to consumer gear that costs five times as much.
I can't really tell if this Tripath sounds fantastic because it's connected to cheap, used speakers (well S$ 3.75 for each two-way speaker is really cheap, so I had no expectations). Also the Nokia E51 is not a good audio source: there is audible hiss during low-volume passages. But then again I also heard hiss from Lalai's iPod Touch 3G during low-volume passages..
In any case (pun intended) all I need now is a good case for the amplifier, then I can go looking for Wharfedale Diamond 10's or something..
