How to target Russian (or soviet) tubes - Transliteration table
Every member can be active here uploading pictures. Only after our work can we enjoy my vision of the following: Instead of sitting in front of a giant puzzle when an untrained radio lover wants to repair a radio he or she should have help.
Where to find what? The member should be able to click the corresponding model page to see whether somebody has already posted some hints (lower part of the page), then print out a possible schematic and also click the tubes on the model page. For each tube the member can get the base connection picture and the tube connection diagram (if there is no schematic). He or she then places them on screen in signal path order and prints them along with the schematic. And there we are!
But it depends on you if that can come true or not. I wish you good success, Ernest (HB9RXQ).
