This includes poor print, oxidized pins, faint discoloration, or poorly box. These tubes were recently tested on a TV-7 tube test Skip to main content.

Power transformer T1 powers all of the power supplies in the Ranger.

5R4, Tube 5R4; Röhre 5R4 ID, Full-Wave Vacuum Rectifier

The tube tests strong and free of shorts. The capacitor further smooths out the variations in the output of the filter choke to produce pure DC. Number of bids and bid amounts may be slightly out of date.

The 5R4-GY can dataaheet up to mA when used with a choke input filter. 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 for transconductance, shorts, gas, leakage and life. All of these tubes have a brown base and black plates.

R35 must be adjusted under the proper conditions to provide the correct voltage to the modulator screen grids. If you have any questions or comments, you xatasheet send E-Mail to Dr. Power Transformer T1 Filament Secondary.

TDSL Tube data [5R4-GYS]

This tube has a low getter. This tube is clean and has no shadowing and label discoloration that appear with extended use. Row 1 left to right: 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.

Works or money back two weeks. Actual rates apply to overseas shipping. 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.

datashdet 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 Power Transformer T1 Filament Secondary: Power transformer T1 also supplies the filament power to all of the tubes in the Ranger. A 5R4-GY rectifier tube is used in a full wave center tapped configuration with a choke input filter. 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. See each listing for international shipping options and datasheeet.
