This tube is clean and has no shadowing and label discoloration that appear with extended use. This includes poor print, oxidized pins, faint discoloration, or poorly box.

The Johnson Viking Ranger – High B+ Power Supply Schematic Diagram and Circuit Description

Skip to main content. Power Transformer T1 Filament Secondary. For sale is a chatham jan-cahg-5r4wga tube. Tested on Hickok A. Construction Highlights – black plates, hanging side halo getter. A choke input filter lowers the peak current the rectifier tube must handle, and increases the overall average current that the rectifier tube can datashert.

All of these tubes have been tested for transconductance, shorts, gas, leakage and life. 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.

Since vacuum tubes were made 30?. The choke input filter allows the rectifier tube to handle substantially more current than when used with a capacitor 5g4 filter.

All of these tubes have a brown base and black plates. These tubes were recently tested on a TV-7 tube test The tube tests strong and free of shorts.

R35 must be adjusted under the proper conditions to dztasheet the correct voltage to the modulator screen grids. All 4 pair have similar results.

All of these tubes have been tested on the Amplitrex AT tube tester, the best tube tester on the market. The capacitor further smooths out the variations in the output of the filter choke to produce pure DC. Also shop in Also shop in.

The 5R4-GY can handle up to mA when used with a choke input filter. If you have any questions or comments, you can send E-Mail to Dr. Row 1 left to right: This page was last updated: The relatively smooth output of the filter choke is additionally filtered by capacitor C However, it is not in its original box so Power Transformer T1 Filament Secondary:
