I started with a factory-made AN DAC 2.1x. First thing I did, was upgrade PS (L-C-L-C), and changed caps and resistors. Then I built a separate mains for the analogue board - and found that my new mains, smaller in size, and supplying higher current to the twin 6922, B+ and filament, operated at lower temp than the factory mains (made by Anglia, it turns out) which was just supplying less than 1/3 ampere to the digital board, so I disassembled the AN provided mains (gauge 30-32, I think) and rewind with gauge 27. I also found out that there remained a lot of space in the bobbin so a made 9 turns/v as against the original's 6.4-6.5. The point is DIY can, and often does, exceed the performance of a factory unit. $200 or $300 makes a lot of difference if you're selling a bazillion units, but not much if you build just one. To AN's credit, theirs is probably the most convenient and the easiest to upgrade ... no trick circuits, everything traditional.

But the amps and Dacs I don't see why these would be any different than factory models. - limono 10:40:24 01/04/08 (7)
