Re: Replacement of selenium rectifier in ST-70. by rossini Sun Nov 05, 2017 10:21 am. Peter W. wrote: Germanium would not be your first choice. Finding such a diode that would be rugged enough is one thing - and the basic characteristics of such a diode in that use would be another. I use a 1N4007 silicon diode in those applications.
The two diodes in the schematic are the selenium rectifier! Just connect your replacements the same way as in the schematic. Yes, but if you're not familiar with selenium rectifiers, the connections can be a mystery. I can certainly read the schematic but I would have needed the same help figuring out the selenium connections.
1 amp or so on the diode is enough. a 1n4007 as suggested is usually a good replacement choice. Resistor is also a probable, since selenium drops more than silicon. A neat replacement option is to install a terminal strip mounted to the chassis where the original stack went and attach the new diode and dropping resistor to it.
I am replacing both the ceramic resister, 50 ohm/10 watts, and the can capacitor, 1000 Mfd/50 v., as well as adding the new BR. If I am replacing the rectifier, I might as well do a general rebuild of the control box. None of the parts are expensive and locating a replacement amp was a far bigger challenge for this jukebox.
Selenium Rectifier Replacement. I have another project radio, a Zenith Model Y723 that needs a new rectifier or preferably, a diode replacement. I looked on ebay for a NOS selenium rectifier to no avail. Zenith has several listed in their parts list such as a Federal 1101A or a Tarzian 100A but I couldn't' find these. The current rating is .071A.
