Greetings!

I have just paid a visit to your site and found many interesting things.

I am a little unclear on the descriptions of some items.
For example, the Amplifier Board in this post,
Is it
1) PCB only?
2) PCB + parts?
3) PCB and parts - assembled?

Prices for this type of amplifier vary widely across the net. I know the picture on your site shows an assembled board but I would just like to be clear.

Regards,

Hi vlakkshepeaudio, you must be not familiar with our style. We are offering blank PCBs online that are 10 times bigger than that one. Do you think we'll charge $3.99 that coin size PCB :D

It's PCB+ parts + assembly, you get everything in that fingers at $3.99.

Sorry for the ceramics..they are just a demo board for phtograph. Caps willl be replaced by film in production.

I've used these tda7297 class AB with great success. You can pick them up as kits from Aliexpress for USD 1.50. Ditch the .22uf ceramics for Russian MBM ally foil and waxed paper or pio's ( I've used both), add some extra tank capacitance on the input rails and use at least 15v 2amp power. For the money, even factoring in the extras I think these tiny amps are astounding for what they cost and I'm satisfied to use this amp in place of several other D class amps, a nice 8 watt SET tube amp I've had for many years, and my venerable old Adcom. Is the tda7297 the best or final amp I'll have? Probably not, but for now it'll do nicely. It really rocks and I listen at loud realistic volumes. Well worth your time to investigate.....

I agree is there a particular website/vender on aliexpress?, had some vender that did not deliver on aliexpress...
 
By typing in **TDA7297 diy kit** in Aliex search box I came up with several entries for around AUD1.85. I didn't buy from them because they don't accept paypal, and filling in all my banking details for a couple of $$ isn't worthwhile. I have used Aliex many times in the past with no issues at all, but for a couple of $$ I use Ebay, where I can pick up those TDA7297 for around AUD4.50, which is still cheaper than dirt...
