I think he has been advise to get some digital drives and about 45V unregulated power supply.
Hi Clive and thanks for the welcome.
Sorry I could have been clearer.
I was just saying that if he`s creating his own unregulated PSU then a nominal output of 45v with no load could drop to below 40v under load and if he goes for a 45v output under load then the PSU may well give more than 50v without a load which may be too much voltage for his drives. I`m not sure what protection they have.
This may or may not be an issue, but I thought I would just point out the possibility.
I apologise if I`ve clouded the issue, that was not my intention.

I`m no electronics expert but that is my experience with power supplies.
