I would prefer to buy the drivers at Zapp but they have only 1 in stock. i phoned Gary but couldn't get through so i emailed him. Apparently the AM882 are discontinued and replaced with the EM806 which is'' the same or better specification as the AM8802 but a newer product'' . any thoughts on this would be helpful .
this is the psu coil Standard Range Toroidal Transformers- CM0750225- 750VA 230v to 2x25v delivery next friday 20th.

cheers for the driver info. i had calculated for 5 motors even though i will only use 4 for the time being . the 5 will draw 13.2 amps @70 vdc hence the 750 VA.
The 625 VA delivers 11.90 amps. i hope my calcs are correct! is there a way around the in rush of current?

Yes Don't turn it ON. . .
You can build an inrush circuit using resistors, thermisters etc but I prefer to avoid this and use smallest transformer possible and then use a C or D rated fuse if still trips which I rarely do upto 625va. Can use slow blow fuses as well.
To be honest I very much doubt you'll ever run 5 Motors at same time that pull full amps at same time so I'd still go with 625Va and 12A.
