Unknown rectifier?
Today thew mail brought me a couple of valves/tubes.
Unfortunatlely there's nothing left of the markings! - So, now im trying to ask the experts at RAT: " Does any of You know what tube it is? " - I think it could be a Philips. This based on the form of the glass, It looks quite like a F443N http://ww.hupse.nl/radio/tubes/F443.htm I have posted a couple of pics at "dk.binaer" under "tube/rör" Can any of you help me raise the glow? Best regards Tonni |

Unknown rectifier?--Mullard FW4/500
Tonni,
these appear to be Mullard FW4/500. They're Philips' AZ50 equivalent but MUCH better sounding. Cheers Dieter Have posted a couple of pics he http://i38.photobucket.com/albums/e1...l/IMG_1294.jpg And he http://i38.photobucket.com/albums/e1...l/IMG_1291.jpg Hope theres any of you that have seen one before...

Hi Patrick! You're quite right! - Pure po.. :-) - By the way. She's 15.5 cm. tall, and some beautifull figures... There's a little quriousity in "her". "She's" a halfwave rectifier!

Have a friend Who's been collecing tubes for 40 years, and he has'nt seen one before... Another friend has been a radioamateur for just as long, and he has'nt either. So... Best regards Tonni Hi Tonni I had been looking before but hesitated to answer because what I found was a halfwave rectifier. Now that you confirm this I am 99% positive in: What you have is a Philips, 4686 It is mentioned in part 2 of the Dutch version of the Philips book "electronenbuizen" ( electrontubes ) in a table on page 304 as a Rectifiertube for "amplifier installations" Kathode 4V - 1,3A Vmax 1000V Imax 75mA Size ( without pins ) 145 x 60mm Pinout is not hard to find out Unfortunately this is all I could find. But the support inside the tube that is visible on your picture is also found in other Philips tubes of the same age and model. Andre |

Unknown rectifier?
DOUV!
Forgot the URL! - It comes he http://www.jogis-roehrenbude.de/Roeh...-Seite/RGN.htm And the tubes were G 4400 & G 4004... - It seems, to me, that it's a G 4004 Valvo. - Dos'nt it? By the way. - Do'nt make serious typing with 3 small kids fooling around your legs! :-D Best regards Tonni Hi again! Think the riddle is solved!!! Fell over the following url where, near the buttom, there's a picture of a RGN4400 and a RGN4004 from VALVO. - What's your opinion? Best regards Tonni "Tonni" skrev i en meddelelse k... Hi again! Many thanx for the infos! - Sounds quite interesting! But! - I just examined the tube again. And I'm sorry to say that i was wrong when posted that it was a half vave.. I found out that the tube has 4 lead's out. 3 at the normal positions and one "hidden" behind the metal-standee. So, it has to be a full-vave after all... By the vay, the pictures i link'ed to earlier, has been moved. - And a couple added... http://i38.photobucket.com/albums/e1...r/IMG_1308.jpg http://i38.photobucket.com/albums/e1...r/IMG_1302.jpg http://i38.photobucket.com/albums/e1...r/IMG_1291.jpg http://i38.photobucket.com/albums/e1...r/IMG_1294.jpg While searching for more info i fell over: http://www.hts-homepage.de/TechnischesMuseum/TM06.html It seems they're also looking for a ansver... :-/ - Look at the right tube in the lover lineup. Now i'm, really, out for a ansver!!! Best regards Tonni "Andre" skrev i en meddelelse l.nl... Tonni wrote: Hi Patrick! You're quite right! - Pure po.. :-) - By the way.
