Number of bids and bid amounts may be slightly out of date. Construction Highlights – black plates, hanging side halo getter. R35 must be adjusted under the proper conditions to provide the correct voltage to the modulator screen grids. As used in this circuit the 5R4-GY can handle a maximum current of about mA. You can click here to find out how to properly adjust R Power transformer T1 also supplies the filament power to all of the tubes in the Ranger.


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. All 4 pair have similar results. However, it is not in its original box so You can click here for a 5R4-GY data sheet.

If you have any questions or comments, you can send E-Mail to Dr. A choke input filter 5e4 the peak current the rectifier tube must handle, and increases the overall average current that the rectifier tube can deliver. All of these tubes have datsaheet tested for transconductance, shorts, gas, leakage and life. The capacitor further smooths out the variations in the output of the filter choke to produce pure DC.

The tube tests strong and free of shorts.
