Strange co-incidence that you should write that at this moment, Lawrence, since I have just completed a repair / rebuild of a Zetagi 20-v. 25-amp. 'solid-state' PSU. Soon I will send in the whole story: I think it'll make for interesting reading. Comes with the cct. diag. too - so D-I-Y copies can be produced!
