No compromise linear power supply for those who want the best.

All JCAT power supplies are assembled by hand with the utmost care to ensure exceptional quality. Such high standards naturally restrict our production capacity and, at times, the demand for our power supplies outpaces this capacity.

OPTIMO 3 DUO is made to order. Current lead time is 4 weeks after placing the order.
