Your amplifier is designed for mains fed applications, the circuit is optimally designed for symmetrical power supplies. Any suggestions on where can I get more informed about it? Cheers, Gnitrops. Anyone can give me a hand, or some directions, here? Thanks in advance. The best solution is to buy an amplifier that need 12VDC power suplly. The K needs a symetric power supply double power supply. If you'll try to use a single supply, you will destroy the amplifier. Using the converters in this application is an inconvenient solution.

Is more simple, reliable and cheaper to buy an amplifier that need 12VDC power suplly. Click to expand Baztien Member. I'm not sure about the insulator. I've got a small transparent plastic sheet with a hole in it. I read insulator can be made of silicone so I'm thinking it could be that but I'd rather be sure. Huntingdon Member. Baztien said:. Many thanks for your quick reply Huntingdon I'm now ordering the equipment and I've got one silly question: Why do we put an for insulator if we want to transfer the heat to the heat sink and this by adding conductive heat paste?

Is it still suitable for this Kit? Besides I'm planning to cut a spare mains socket cable to figure 8 as my mains cable to my transformer is it ok? More precisely it's a 72VA 12V 3A is it too much power? The 72VA transformer will be fine. You're getting more transformer than you paid for, and with the price of copper as it is these days you can be happy. Show hidden low quality content. Resistors 4. PCB tabs Watch the polarity!
