  1. Can this be done independent of the other mods? What are the labels on the board? C1 and c3?
  2. Thanks. Opened the cabinet and saw red dots on the woofer, which I believe indicated positive. Much more full sounding now.
  3. 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.
  4. Try a sure tpa3110. For the price around $10 plus a power supply you can't go wrong.
  5. 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.
  6. Input 100-240V 50-60hz .6a Output is 12v 2amp . Model number is ksas0241200200d5 Looks like this - http://www.google.com/imgres?imgurl=http://azsurplus.com/images/KTEC_KSAS0241200200D5.jpg&imgrefurl=http://azsurplus.com/index.php?main_page%3Dproduct_info%26cPath%3D1_14%26products_id%3D6818&h=768&w=554&sz=47&tbnid=Di7qmv8UAhMYsM:&tbnh=90&tbnw=65&zoom=1&usg=__jU-EMyL6IZduNtgShqVCJ46D_nE=&docid=iQEAB6tcEVcyDM&sa=X&ei=j4-FUqjvE4bhyQHiyYCQDA&sqi=2&ved=0CEkQ9QEwAw I wasn't sure if the plug would fit. Hope it does!
  7. 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.
  8. 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.
