Dec 29, 2024 · The Selenium-Rectifier has a lot of Internal-Resistance as well as a substantial Forward-Voltage-Drop. This "old-style" "Power-Supply-System" depends upon this Resistance …

Aug 31, 2019 · A bridge rectifier built of discrete diodes will take up far less space than even one selenium rectifier. And if any service would be needed in the future there are many silicon …

Aug 15, 2017 · The old Selenium rectifiers are not very efficient. The new bridge rectifier is the reason you are getting a higher voltage. Probably a little high a voltage. Be great to get a flat …

Sep 6, 2023 · A point to note when replacing Selenium rectifiers with Silicon, is the high forward voltage drop of Selenium compared to Silicon. This will result in a much higher DC supply …

Jul 14, 2024 · I'm fixing a Radiogram with a valve amplifier. It has a selenium rectifier, ITT SenterCel type C2D. Does anyone have any spec? I'm thinking of replacing it by a 1N4007 …

Re: Selenium rectifier replacement Selenium rectifier! Now there's a collector's item. It's amazing how small (physically) a diode can replace one of those antiques. Your SN is too old for it's …

Apr 7, 2024 · The recondition consisted of replacing the selenium rectifiers, cleaning the switches, and new cords for both the battery side and the line cord. On several units since then the main …

Dec 31, 2012 · Re: Kohler 7.5 CMK 21 rectifier replacement Nice post, and one that is pretty generic relative to the substitution of a bridge rectifier for the old selenium rectifiers.

Jul 17, 2020 · The secondary of the transformer is connected to the full-wave selenium rectifier to produce a DC current that is supplied to a auxiliary winding to counteract any droop in the output.

Oct 9, 2008 · The selenium rectifier has built in resistance that limits current flow, silicone rectifiers on the other hand have very low resistance in order to use one the least you need to do is …
