Traductor Please !!!
I need a translation, how do you called in english the "thing" who control the quality of tubes:
--valves meter ?
--tubes meter ?
I want a buid one, but I donīt know how you call it...
Or maybe you can give me plans, direction, e.mail etc...etc... for make one
Something like that..
The 2 terms that come to mind are:
Valve tester (UK English)
Tube checker (US English)
Try a Google search with either string; Lots of results :)
I suppose one of the classic designs such as AVO or Taylor could be partially copied for measuring anode current and gm . Measuring leakage would be another matter and would complicate the design greatly . If using only 6.3V and 12.6V filaments and anode/screen voltage of 100 and 250 , it could be built very simply . Most types could be tested this way . The main disadvantage to a DIY design is calibration and how to implement each socket/pinout (I would suggest a single octal socket and build an adapter for each type)
How do you check your own tubes: Whatīs your method ?
Do you need one?
Substitution is the best method for me.
I've usually determined that one is faulty (by voltage measurements) before removing it.
Of course that only verifies that it is good under the present condition.
For a seller: A tester is essential.
Re: Do you need one?
I use a tester and i'm not a seller...;)
I wanted to make one in case of recuparation af old valves, and avoid making a amp with bad valves.
I test it before make it...
But also I reealise itīs imposible to have any plans on the net..I was looking and looking and nothing
PLEASE, if you have any ideas, let me know
Thanks in advance
Tesatador para tubos electricos.
No necessitara construir este testador lo que es cosa bastante complicada, seria mucho mas facil comprarlo en los Estados Unidos o en Inglaterra, por ejemplo.
Usted deberia tener cuenta de la tension red AC de los U.S. que no corresponde con la nuestra.
En los U.S. se utilisan 115/120VAC y en Europa 220/240 VAC., sin duda lo sabe ya usted.
Marcas connocidas son AVO, Hickok y muchas otros...
Lo mejor seria, en mi opininion de comprar algo mas recen como este que hacen la gente de Trancendent Audio.
Si necessita mas informacion, por favor, que usted lo diga.
Con mucho gusto y desculpe usted mi Espagnol llenado de faltas,
English translation for other members on request. ( I'm feeling laZ)
There a couple "tester" kits on the market. Hagerman & Rosenblitz to name the 2 i know.
I have also seen a chapter in an old radio manual on building test rigs for tubes. And attached is a pic of a simple tester from a letter to the editor in Glass Audio .
