Re: Russian valve tester
I should add - further to my post #20 - that the russian site shows the valves that IL-13 will test (it doesn't say whether thats an "exhaustive" list or not).
I recognise the some of them, like the 6F12 (EF91), 6K7, and 6F7 - however there are a lot of others that appear to be peculiar to the russian market, presumably from the Cold War era, when their technology was virtually unknown in the west. Having said that, I am hardly an expert on valve types, and I just note that valves like the "6ZH1B" don't appear to produce any hits on western sites dealing with valves, such as the National Valve Museum.

while poking around russian websites I came across this one (russian) or the Google translation of it. My reading of the very quaint english translation suggests that the tester you may be referring to would be the L3-3 model, which has its own page here. Whether this one is "better" than the AVO, etc, will depend on what criteria of goodness you are applying.... Richard |

Re: Russian valve tester
Nice looking machine
I feel you will need to do some detective work to find out what part of the card determines each function of the valve. Filament voltage is obviously important - I suggest if you know that the card for the 6F12 (EF91) should set that to be 6.3 volts, verify that on the valve tester, then determine how that is setting the voltage within the tester itself. Once you know what track (hole placement) sets that voltage, you could start to make your own cards. Diodes valves are simpler - so if you can determine which card relates to a diode valve, it should have less holes on it, as they will relate to less parts within a valve. Interesting work! SEAN

Re: Russian valve tester
Hi James! Please can you post photos of the insides showing the construction, thank you!

Re: Russian valve tester
James' thread has opened up quite a few eyes to the existance of a wealth of eastern european valve testers. Many of us VT enthusiasts have, for many years, been preoccupied by UK models - AVO, Mullard, Taylor, etc.
Reading through the Jacmusic lists, and having actually spoke with Denis Tabor in the past, plus gleaned all this info in recent days, has made me realise how much there is still to learn. Hopefully some of the Mullard HSVT buffs out there can give James some hints on making cards. Obviously I realise that their electro-mechanical system is more complicated than the Russian manual plug-in system, but a robust card material would still be needed. Regards, David |

Like you I like playing with Valves and testers, looking at the UK and US ones is just the start, I would love to get my hands on a L3-3 to play with but I found the price a bit steep and didn't fancy the hassle of importing from Russia or the Ukraine. That why this thread is so interesting.

Re: Russian valve tester
Hi Richard
thanks you for your input the problem with trying a translation is that my English keyboard does not have Russian letters The cards are numbered 1-140 and have Russian language printed on them. thanks again MM0HDW |

Re: Russian valve tester
I suspect what's needed is not translation, but transliteration whereby letters from the Cyrillic alphabet are transliterated to our alphabet. The only letters which are the same are A, K, T, M and O.
If you can post a picture of a few cards I'll try to help.

there are a number of ways around this problem: 1. You can just copy and paste existing russian text on someone's webpage - which is what I did for a google search to find those russian sites that I offered above. 2. You can install a russian keyboard on your PC - I suggest googling for your particular OS to find out how to do that. I have just set it up on my Win7 PC, and just by pressing Alt+Shift, I can go straight into russian squiggles: 8у3иащг8ер9щ34 !! 3. You can use a "virtual russian keyboard online: https://winrus.com/keyboard.htm - then copy and paste the characters you write into Google translate to get an English translation of them. To deal with your cards in Russian, you could use method 3 above, and just copy out the text you see, and then translate it. If you have the facilities (as I do) I would scan the card, then OCR it (I use Abbyy Finereader), setting the OCR program to recognise Cyrillic characters, and then put that into Google Translate to get an english version.

Re: Russian valve tester
Google Translate offers a Russian keyboard, have a look at the included screenshot. You access it by pressing the small keyboard symbol in the lower right corner.
I sometimes scan Russian books and datasheets, then run the scanned images through Abbyy Finereader to get the Russian text into a word document which I then use Google Translate to get into English. There are also some online PDF creating webpages that will do OCR at the same time, then you can cut that OCR text into Google Translate. If you have access to a full version of Adobe PDF Pro you can do similar OCR manipulation there too. /Martin

Re: Russian valve tester
Hi Chris
Yes the one I have is definitely the TubeTester IL-13 - ИЛ-13 and quite different to the L-3. The only place I see it is the radio Museum site you gave me. the cards in this tester are half the height of the ones shown for the L-1 and L- so far have not found a site with these cards, only the large cards. ? |

Re: Russian valve tester
I didn't know you could do that! I mean I knew about Google translate but I didn't know it could resolve the characters automatically.
My 'manual' transliteration from the Cyrillic yields: 'RSFSR SIC'H Malogabaritnyy ispytatel' lamp...' ='Russian Soviet Federal Socialist Republic ... [unclear what Sic'h is but it's hard to transliterate 'X' phonetically) small-sized tester lamp' My Russian is very rusty and never was that sparkling... good to know there are bulk ways (so it seems) of deciphering the cards.

Re: Russian valve tester
Perhaps some of the valves can be found on http://gstube.com/index.php
I've got some weird Russian stuff from there for attempting circuit design, and most valves have datasheets which could demonstrate what they are, or what they're equivalent to in Western terms. |

Re: Russian valve tester
The IL13 and the L3-1 or L3-3 are completly different,
Dont't use the wrong test cards. In the TESTCARD Set is one Master card (Testcard) to generate your own card. A description of the IL13 ist here http://www.magictubes.ru/text/app/il13.htm Of course in russian, but can translate the site with Google or what ever you have. Change some words (lamp--> Tube or valve) and others. Print the translated site and you have a short description of your system. Combi tubes (double triode ECC or EABC etc) are tested separat, that means you need two cards or more for one tube. Power range for Power tubes is 40W. Allways calibrate Line Power at first before testing. Peter |

Re: Russian valve tester
James
I just came across this German site with Info on the L1-3 http://www.jogis-roehrenbude.de/Roeh.../L1-3/L1_3.htm Use Google translate. It has internal shots and indicates that in operation and the cards it is very similar to the L3-3 along with info on producing the cards.

Re: Russian valve tester
Chris,
we are talking about the IL 13 - not about L1-3 or L3-3. They have nothing in common. IL 13 is a Good / Bad tester and L1-3, L3-3 are tester for tube parameters. IL14 is the newer version. On Youtube you can find some clips about IL13 and IL14 The IL13,14 tester were build for the russ. military for quick and simple tube testing in the field (air field). Peter |
