A few years ago I started to make a small combo amp for practicing in my bedroom. Due to starting a family I ran out of time and abandoned the project, but not before building a nice pine cab based upon the Fender 5F1 combo.
I now want to complete the project as a 5W SS Champ style amp. I have ordered one of these cheap TDA2050 boards form ebay http://www.ebay.com.au/itm/DC-12-24V-5W-120W-TDA2050-Mono-Channel-Audio-Power-Amplifier-Board-Module-kit-/142443279688 which from the TDA2050 datasheet will deliver about 5W into an 8 Ohm speaker at 18V single supply (I have some old 18V 4A laptop power supplies). I don't really trust the claims of 12-24V 5W- 120W, but happy to be shown wrong!
Could this project be as simple as (input -> Fetzer valve -> TDA board -> speaker) or do I need to put a buffer in somewhere? Also when running a fetzer vale at 18V, do I bias the transistor at 9V? (I obviously need to do some homework).
Does anyone have any experience using these prefab boards?
