I do have information about the earliest USSR semiconductors. If you want to know about them,
I am still seeking some early USSR semiconductors, in particular:
- С1Б, С1В, С1Г, and С1Д
- С2В and С2Г
- С3Г, С4Б, С4В and С4Г
- П1Д and П1И
- П5Г and П5Д
- П6Б
- П10А and П11А
- П13К
- П14Б
- П26А, П27 and П27Б, П29А
- ФТ-1, ФТГ-2, and ФТГ-3
- diodes ДГ-В1 to ДГ-В8 and СД1
- any ВГ-n diode e.g., ВГ-5
If you know where I might obtain any of them,
