[Amps] Price per Watt Conversation

[Catherine James]

Manfred,

   So would it be better to use 4 or or more devices with somewhat lower ratings for linear operation?

   Is there a cheaper option to use simpler heat sinks that don't have to be carefully machine, but push them less hard by spreading the power over a larger number of devices?  What's the practical upper limit of devices that could be used before creating other design problems?

73,
