Quenton, you could always opt for a switched mode power supply. The output voltage is a lot more stable ! As you probably know, I use an SMPS500R and I'm very happy with the performance of that power supply. I would adivice everyone to go down the SMPS route !

Any word from Clemens or Ton? Am testing with an old 35V tranny. 36.52V AC measured at bridge input vs 48.9V DC measured across the PS caps.  I'm using two bridge rectifiers per channel so it's not surprising that my losses are quite high: 2.74V. So I'm currently looking at increasing to 38.6V Sec (on load) with <6% regulation. The worst case maximum @ 253V would be 58.13V. Is this a problem? Such supply is very unlikely and all my heatsinks are oversize.  Nominal supply voltage in this case (@ 240V) would be 55.0V (no load). I'm probably being paranoid but the costs are considerable so I do not want to make a mistake. Thanks! Q.

Finally I managed to make a very short intro video of EEZ Studio. A more videos will follows and its source code will be uploaded on the GitHub in near future.https://www.youtube.com/watch?v=gfUSl8hXwjE
