In offer is a L3-3 NEW tube tester technical and operating manual in English.

The Manual (published 1979) was completely recreated. You will receive a bound copy with 114 pages in A4 format, and 2 pages in A3 format. It includes a user manual, newly drawn main switch diagram, and all newly drawn basic circuit diagrams. All in all the 19 original attachments. 

In addition, there are 3 new appendices 10, 21 and 22 which include the list with the additional instructions on certain test charts, a tube comparison list by ELORG (Russian and international types) and a table of the connection possibilities of the tube socket to the switchboard.

All tables and lists were converted into readable text in the main text and in the annexes.

The only images that I scanned from templates and edited in the manual are:
1. General view of the device (Chapter 1)
2. 2 chassis images (Chapter 3)
3. View of the front panel (Appendix 2, the front panel  was completely covered with English text )
4. Wiring diagram of the tube stabiliser (Appendix 13, the item numbers incl. Component values have been newly incorporated)

Since the entire document is in Word format. It is now possible to make extensions, or to correct any errors.

 Language: English. In some pages in addition to English also Cyrillic.

If desired, more detailed photos can be made. If you're interested just contact me.
