Thanks. Opened the cabinet and saw red dots on the woofer, which I believe indicated positive. Much more full sounding now.

I have a set of 1981 khorns. No manual. I want to make sure the woofers are connected to the crossover properly but I don't see any markings on the woofer connection.
If I'm facing the woofer is the right or left connection positive?
I could try a battery but worried about damage and I'm not sure I could see it move anyway.

Try a sure tpa3110. For the price around $10 plus a power supply you can't go wrong.

I hooked up my TDA7297 using the Dayton DTA-1 power supply. I hooked the amp up to my Khorns and my ipod. It sounded pretty good, more full sounding than the DTA-1.
I then hooked up my preamp, which is a McIntosh MX1113. Ipod to Pre, pre to TDA 7297 to Khorns. Whoa! Bass city! Sounded fantastic. I can't wait to hook up my SACD player and my turntable.
Question for everyone - how and what are you using to mount the TDA7297? I was thinking of finding a small wood box of some kind. I'm not sure how to orient the amp,. Also, the speaker connection is quite small . I bought some wire and I'm thinking of hooking it to banana plug inputs.

The DTA-1 power supply should work. Can you share the specs that are usually written on the bottom of the unit?
Input 100-240V 50-60hz .6a
Output is 12v 2amp .
Model number is ksas0241200200d5
I wasn't sure if the plug would fit. Hope it does!

I am interested in trying the TDA7297. I found the home mart usa seller and plan to purchase one . Any recommendation on power supply? I'm looking for a wall wart.
I have used a Dayton DTA-1 with my Klipschorns. Without my preamp (mcintosh MX113) the bass is a bit weak.
The recommended power supply should be capable of providing 12V DC and 2A. I use a modified 110 watt Switch Mode Power Supply (SMPS) that has a regulated 12-13V DC and 3-4A output. The amp can actually be driven with anything from 12 to 16V DC. If you can find a laptop power supply or an LED monitor power supply that fits this range, that should be good for starters. These are usually SMPS and should work well.
If you are a DIY audio person -- especially with working safely with power supplies -- I would recommend the Mean Well RS-100-12 SMPS. You will need to put this in an enclosure and also add the following:
- Power switch
- IEC inlet
- DC power cable
With the right power supply, this amp will provide more bass and musical body than the Dayton DTA-1 amp. From what I know, the Dayton DTA-1 is basically the same as the original Sonic Impact T-amp using the Tripath TA2024 Class D chip. I have a Sonic Impact Gen 2 T-amp, which I have modified, and it still doesn't sound as good as the TDA7297 amp in stock form.
I have since replaced the stock Polyester input coupling caps with Panasonic Propylene film and foil caps, and the sound quality has reached a new level. I have some Mundorf Supreme film caps and an SMD resistor-based stepped attenuator on the way. I have high expectations for taking this amp even further.
I've even connected this little amp to my Audio Research PH5 phono stage, and I've obtained great results. This is a very musical amp, and it's so inexpensive. It doesn't beat my Audio Research LS7 and restored and modified Dynakit Stereo 35, but it's able to hold its own.
Thanks! I am looking forward to trying it out in few weeks when it arrives. Do you think the power supply that came with the Dayton DTA-1 would work? I probably have a laptop power supply laying around somewhere.

Can this be done independent of the other mods? What are the labels on the board? C1 and c3?
