A few restoration questions-- rectificiation, B+ voltage, etc

[Tom Bavis]

The schematic is online here: http://techpreservation.dyndns.org/s...ics/Zenith.htm

You'll need to get the DjVu plug-in or IRFANVIEW with its DjVu plug-in to open it. http://www.celartem.com/en/download/djvu.asp

No need to add a resistor - the tubes will take the extra voltage from a silicon rectifier just fine (though some radios need a bit more caution... battery / AC ones especially)
