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,
blakkshepeaudio

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

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.

It sounds fairly good for non hifi applications. What do you anticipate for a 3.99$ gadget:-)
