I'd like to build best quality, no compromise power supply possible so here are my questions:1. what secondary voltage transformer do I need? I guess 2x24V will do.2. phono preamp draws approx. 25mA per rail (DACT CT100). Would 10VA transformer be an overkill?3. what is the benefit of installing parallel rectifier diodes 1N5404G as shown on the schematics?4. what type 5W resistors should be? are wirewound types OK?5. does LT1028 produce better results than AD8256. due to relatively low current draw of 25mA can I use smaller heatsinks (14 C/W). if so, I coud install two units one on top of each other in 2U enclosure http://export.farnell.com/jsp/search/productdetail.jsp?sku=1892326Many thanks for your input,Goran
