Default DTA-2 T-amp PC board

Whoah check it out. Dayton is now selling their little T-amp without the case for less than 20 bucks.

I'm guessing it probably doesn't come with the wall wart, so a power supply of some sort will be necessary, but for doing little computer speaker projects this looks like it'd be absolutely perfect! Even comes with the volume control. 20 bucks!

I've used a couple of the DTA-1 T-amps and they're fantastic little things. This has me excited

I just received a Sure TA2024 board. The build quality is considerably higher than the SI/Dayton PCB. The price is the same, and the Sure's screw terminals will be handy for many. The Sure also has more optimally sized input caps, so it doesn't require modification to produce deep bass. Of course, you need to buy your own pot, but $2 will eclipse the quality of the one included with the SI. Some folks also prefer to remove the input low pass filter from the Sure, a mod unnecessary on the Dayton.

Don't get me wrong, the Dayton is a wonderful little amplifier. I think it competes favorably with very expensive solid state. However, for DIY purposes, I think the Sure board is the way to go. And unless you need to use batteries, the enclosed Sure units are better looking that the Dayton's plastic case and also $40. The SI is smaller, which might be an advantage from some. Not the mention the cheap and quick shipping from PE, as compared to choosing between cheap and quick from China. And I do recommend the Dayton to customers for use with a single driver open baffle, as the rolled off low bass is actually beneficial in that app (to avoid wasting excursion).

Hey Paul,

How come every time I explore a cool idea I see you have already been there?

I really like the Dayton "SI' board with the Betsys.
