Tube 5R4G or Röhre 5R4G ID4523, Full-Wave Vacuum Rectifier, Octal (Int.Octal, IO) K8A, USA 1935 and Power-supply shown. Radio tubes are valves.

The 5R4GY is a high voltage power rectifier and was designed for transmitter use. It has a rating of 180 Watts. The maximum reservoir capacitor is specified at 4 µF and the rectifier needs a series resistance of 250 Ω to limit peak current. See also 5R4WGY for …

2013年3月2日 · 旁热式5AR4是一个比直热式5U4G先进一些的管子，它们之间通常不能互换，因为特性差距太大了，5AR4的压降是17V，而5U4G的压降是58V；还有就是灯丝加热电流，5AR4灯丝是1.9A，5U4G的灯丝是3A，如果变压器灯丝绕组容量不够的时候，灯丝电压的下降会使5U4G的灯丝加热不足，压降则会更大。 您有没有在换用不同整流管时，测过B+的电压？ ，没有。 旁热式5AR4是一个比直热式5U4G先进一些的管子，它们之间通常不能互换，因为特性差距太大 …

2015年1月22日 · 5R4 has considerably more voltage drop, so output voltage will be lower, all other things being equal. It's peak repetitive current rating is slightly lower (650 mA vs. 750 for 5AR4). Peak repetitive current is a spec that should not be exceeded; arcing may result.

2009年4月16日 · ANyone know the differences between the 5u4g series and the 5r4-gy rectifier tubes? They use the same settings for testing on my mighty might tube tester. There is clearly an additional part in the 5r4-gy tube though. See the pics the 5r4 is on the left. Glory or Death! A good resource.... Rockin and Rollin....

2013年12月10日 · Hauntingly beautiful tone, lots of air, great layering, transparency above the rest, and just perfect extension in both the highs and lows, deep bass, palpable, lucid midrange, holographic 3D staging and imaging (like with the WA22 and Glenn OTL, the image is very life-like and out of head unreal good at times), amazing!

LM2575D2T-5R4G Product details The LM2575 series of regulators are monolithic integrated circuits ideally suited for easy and convenient design of a step−down switching regulator (buck converter). All circuits of this series are capable of driving a …

2014年11月1日 · The 5R4WGB was a ruggedized version of the 5R4GB specifically designed for use in military B52 bomber aircraft. It has an unusual shape, thick glass, and a molded base that extends partially up the sides of the glass. This shape has given it the nickname "potato masher".

2022年8月15日 · 电子管参数输出电压12v电子管，是一种最早期的电信号放大器件。 被封闭在玻璃容器（一般为玻璃管）中的阴极电子发射部分、控制栅极、加速栅极、阳极（屏极）引线被焊在管基上。 利用电场对真空中的控制栅极注入电子调制信号，并在阳极获得对信号放大或反馈振荡后的不同参数信号数据。 亲，很荣幸可以回答您的问题哟~老师这边给您查到的信息是：5R4G电子管参数：5R4G电子管参数是是直热式双二极管,灯丝电压 5v2A,最大阳极交流电压2x900V,平均 …
