Weber VST Copper Cap Rectifiers
Weber Copper Cap Rectifiers are solid state rectifier replacement devices for use in place of vintage tube rectifiers. Each model emulates the forward conduction resistance curve of the tube type it replaces and also has linear in-rush current limiting to simulate the warm-up of a tube rectifier, however, it is in the 1 to 2 second range, rather than the 7 to 9 seconds of a typical rectifier tube. The envelopes are solid hard-drawn copper with a high thermal capacitance that allows a 100% continuous overload condition. The Copper Cap emulates a tube rectifier, but it does not require filament power. In the case of a 5U4, for instance, this is a savings of 15 watts. The power transformer will run cooler and last longer. While the filament and coating on the cathode of a tube rectifier are destined to eventual failure, a Copper Cap will last the lifetime of the amp when used properly. Additionally, close tolerance parts are used in all Copper Cap models, no hand sorting is necessary.
