Default Velleman 230W amplifier

Have anybody built this amp as Velleman kit? I am interesed in his sound quality and power rating.

I will use him in my small working room at moderate listening levels with small sub-sat system,but I am not sure if this is the right thing.

Default TDA1521

This Velleman kit is just a basic TDA1521 application (also see http://www.semiconductors.philips.com/pip/TDA1521Q ).

I once built a little amp around it for my PC (not the Velleman kit). Seems quite OK, nothing spectacular, but decent.

Regards,
Dirk

Hi supernet

I've built the Velleman K4003 - its works great is is very cheap, all you need is a case and a transformer (50VA 12-0-12V).

Be aware that its rated at 2 x 10W into 8 ohms or 2 x 15W into 4, but that should be ample for your application. I say go for it.

Hope this helps,
Tim.

Hi,

Anybody can recommend a trusteable powersupply (AC/DC regulator) PCB or assemblied KIT for the Velleman kit ((IC based) with 10 Watts RMS per channel ?

What I 'm looking for is anything suited to be used with a transformer with more units to be added (hey ..you got it....until I can fulfill Home Theater 5.1 specs)

Would work a wallmount transformer (for testing) as it is usually non filtered ?

Thx.
