Web13 mei 2024 · It's not that hard to replace a selenium rectifier. You really just need to make sure at the end of it all your B+ is in spec, which usually means you'll need to add a resistor of some sort in series with your new diode to achieve the proper result. I'll add the diode and too much resistance at first to get a baseline measurement. Web15 aug. 2024 · Selenium rectifiers have a much softer I/U characteristic than silicon ones. You can simulate the soft slope behaviour on the right by putting a few ohms resistor …
WebDave, measure the ac voltage going into the selenium rectifier to get an idea of the voltage rating to replace the selenium. I would thing a 1 amp unit would be large enough, but full wave bridge rectifiers are cheap enough so go for a higher amperage bridge at what ever voltage you need. Sal philo 15 years ago ...
