The 5R4-GY can handle up to mA when used with a choke input filter. R35 must be adjusted under the proper conditions to provide the correct voltage to the modulator screen grids. Power transformer T1 also supplies the filament power to all datasheeg the tubes in the Ranger. Number of bids and bid amounts may be slightly out of date.

Datasyeet includes poor print, oxidized pins, faint discoloration, or poorly box. For sale is a chatham jan-cahg-5r4wga tube. Row 1 left to right: Works or money back two weeks.


These tubes were recently tested on a TV-7 tube test All 4 pair have similar results. As used in this circuit the 5R4-GY can handle a maximum current of about mA. Also shop in Also shop in.

You can click here for a datashee data sheet. The tube has a directly heated cathode, which means that a separate filament winding on the power transformer must be used, since the cathode is not at ground potential.

The tube datahseet strong and free of shorts. Tested on Hickok A. The capacitor further smooths out the variations in the output of the filter choke to produce pure DC. You can click here to find out how to properly adjust R This tube has a low getter. The choke input filter allows the rectifier tube to handle substantially more current than when used with a capacitor input filter.
