Components, required for the high-quality DIY build are specified in "WHAT TO ORDER" section of the table below. In addition to that, you need to buy the transformers (2 x 250VA, 2 x 36V AC toroids) and the case (3U tall with good heatsinks). We deliberately don't offer the transformers and the case in our store as it's much more cost-effective to buy them locally.
