As used in this circuit the 5R4-GY can handle a maximum current of about mA. If you ddatasheet any questions or comments, you can send E-Mail to Dr.

This page was last updated: See each listing for international shipping options and costs. These tubes were recently tested on a TV-7 tube test The tube has a directly heated cathode, daatsheet means that a separate filament winding on the power transformer must be used, since the cathode is not at ground potential.

R35 must be adjusted under the adtasheet conditions to provide the correct voltage to the modulator screen grids. A choke input filter lowers the peak current the rectifier tube must handle, and increases the overall average current that the rectifier tube can deliver.


However, it is not in its original box so Works or money back two weeks. Greg Latta at glatta frostburg.

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

The relatively smooth output of the filter choke is additionally filtered by capacitor C All 4 pair have similar results. Since vacuum tubes were made 30?.

The tube tests strong and free of shorts. All of these tubes have been tested for transconductance, shorts, gas, leakage and life. This tube has a low getter. This includes poor print, oxidized pins, faint discoloration, or poorly box. The capacitor further smooths out the variations in the output of the filter choke to produce pure DC. Power Transformer T1 Filament Secondary.

This tube is clean and has no shadowing and label discoloration that appear with extended use. Browse Related Browse Related. Power Transformer T1 Filament Secondary: 55r4 of these tubes have a brown base and black plates. The choke input filter allows the rectifier tube to handle substantially more current than when used with a capacitor input filter.

All of these tubes have been tested on the Amplitrex AT tube tester, the best tube tester on the market. Also shop in Also shop in. Darasheet can click here to find out how to properly adjust R Tested on Hickok A. The 5R4-GY can handle up to mA when used with a choke input filter.
