Sorry Peter I got confused over the numbering.

Hi Guys
Sorry for delay with the requested photographs.

I have looked at the circuit for the tester and yes it is possible to make cards, very laborious and as the tester is not mine I will not make cards, however one can just insert the required pins in the correct holes, check that the volts are as required on the selected valve base and test the valve, long operation.

Now I can not get the photos to appear on the site, I have loaded them BUT?

I see that you posted pictures in Post 1 so just a reminder that you need to select "Go Advanced".

Yes it's possible but very tricky.
First, the 'BUS' goes not from socket to socket PIN 1 to PIN 1.

The Il13 was not constructed to test all Tubes, maybe only the tube the use by Mil.
Thats why not all pins go straight to the panel (switchboard).

Best is, to use the Master card and compare with the cards from the set.

Also, there are two errors in the schematic !

The numbering for the heater pins on the switchboard is not 1 to 6,
it is 1 to 4 and 5 to 6.
Here you can see that only some pins (standard tubes) connected for filament.

To make a new card, it is nessesary to start with one socket (ex Panel 11, 8 pins)
and use a already made card, print the tube schema, and follow the bus/lines to the switchboard numbers
and compare with the circuit diagram.

1-6 Filament pins
7-12 Gate 1 pins
13-19 Kathode pins (to ground)
20-26 Anode pins
27 Bridge R9 (short)
28 Bridge R8 (short)
29 switch on heater (tube L1)
30 Diode measurement
31-36 puls. Gate 1 bias (-35 to -1V)
37-41 Gate 1 (10 to 0,6 V ~)
42-50 Filament voltage (1,2 to 30V~)
51-54 and 57-60 Anode voltage (65-185V)
55 + 56 Shunt
61 Filament indirect
62 Filament direct
63-66 Anode voltage (6,3 to 20 V) for diode
67 Kenotron (6,3; 12,6; 20, 30, 67, 125, 155, 210 V)
68
69-72 Anode load for Kenotron (0,2-2 Kohm)

Then you see what is why connected.

Do the same with socket 10 (Panel 10)

The higher voltages are stacked voltages.

On the cards are the value for LIMB
LIMB is set with the potentiometer with scale, like in US testers.

Test for russian letters here:
Лампы накаливания - filament
смещение - Bias
прибора накал - Filament on
косвен. накал - Filament indirect
нагрузка (ком.) - Anode Resistor
кенотрон - Kenotron

Btw. the letters AEKMOT are the same in latin is not correct,
they are used in the same way (only upper case) but have a different code
(a K is not a K if you type it) and the lower case letters are completly different.

Peter

Thank you Peter

yes, that is what I found and you have gleaned so much more info.

The tester was saved from the skip by a local man who asked me have a look at it, I have along with you guys spent a lot of time on this but he says he now wants me to sell it for him as he does not use a computer.

I don't want to fall foul of the rules, but if he doesn't use a computer you may wish to advise him of the difference between 'advertised' and 'sold' prices before he gets too excited.

The usual price for this device is not so high, so maybe keep it ,

Another problem ist the Transformer - once overheated......

I was writing Cyrillic letters using pen and paper long before computers were in common use.

E may look the same, but its phonetic sound is different. The same goes for B, H, P, C, Y and X.

Interesting is,
the russian language has a lot of german (from Zar Peter)
and french (from Napoleon) words
and elektronic is mostly the same meaning -
so russian is not so difficult ).

Likewise, for those of us who learn't a smattering of Greek(whilst stationed in Cyprus for three years), a number of written words & numbers, etc., are similar.

Yes, I have told him that it is a unknown and as far as I am concerned not really the easiest tester to use unless one has the correct cards, however he has been ADVISED that it is rare and worth a lot.

Lets face it, he got it out of a skip so anything is a profit for him.

It's amazing how that advice is more potent than your pragmatic and first-hand counsel!

Its value is probably severely compromised by the lack of the cards.

Once someone thinks they have scented a treasure trove, and the light of unreason illuminates their eyes, there is not a lot you can do. They've had advice, they've had first-hand counsel. They have to make their own mind up, but I think they are likely to opt for their own first-hand experience.

If they can't get the thing to do what they want, then it becomes their turn to try to convince a subsequent purchaser that it's rare and very valuable...

It's a situation we all keep finding ourselves in, and it's difficult to not get enmeshed.

We'll see. As the tester is now on eBay I'll close the thread: https://www.ebay.co.uk/itm/RUSSIAN-I...QAAOSwggRfvBCU
