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 datadheet at ground potential. Power transformer T1 powers all of the power supplies in the Ranger. All of these tubes have a brown base and black plates.

Power transformer T1 also supplies the filament power to all of the tubes in the Ranger. Power Transformer T1 Filament Secondary. All of these tubes have been tested for transconductance, shorts, gas, leakage and life.

If you have any questions or comments, you can send E-Mail to Dr.


Tested on Hickok A. However, it is not in its original box so Browse Related Browse Related. This tube has a low getter.

IPZ40N04S5-5R4 Datasheet PDF

All of these tubes have been tested on the Amplitrex AT tube tester, the best datasueet tester on the market. This tube is clean and has no shadowing and label discoloration that appear with extended use.

The choke input filter allows the rectifier tube to datsheet substantially more current than when used with a capacitor input filter. Works or money back two weeks. This includes poor print, oxidized pins, faint discoloration, or poorly box.

TDSL Tube data [5R4]

Construction Highlights – black plates, hanging side halo getter. All 4 pair have similar datasheeg. You can click here for a 5R4-GY data sheet. 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 Power Transformer T1 Filament Secondary: Skip to main content.

Row 1 left to right: As used in this circuit the 5R4-GY can handle a maximum current of about mA. The relatively smooth output of the filter choke is additionally filtered by capacitor C The 5R4-GY can handle up to mA when used with a choke input filter.


Number of bids and bid amounts may be slightly out of date.

R35 must be adjusted under the proper conditions to provide the correct voltage to the modulator screen grids. These tubes were recently tested on a TV-7 tube test A 5R4-GY rectifier tube is used in a full wave center tapped configuration with datasbeet choke input filter. This page was last updated: The tube tests strong and free of shorts. For sale is a chatham jan-cahg-5r4wga tube.

See each listing for international shipping options and costs. 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.

Since vacuum tubes were made 30?. Actual rates apply to overseas shipping.
