A postwar ZW will fit the bill perfectly for the OP question. 10-14 amps total output, 4 variable outputs for flexibility and accessories, 2 of those with whistle controls. AND all of the transient voltage suppression for protecting modern electronics that your recommendations have(none). You can buy three of these in good working condition for the price of just one GW-180.
(Circuit breakers are for overloads, not for protecting against damaging, cumulative, voltage spikes which are ongoing... even in the absence of an overload/short/derailment)
