Notes

EPM101G

• The second to best tier of the grading system for the EPM101G tube series is interchangeably referred to as C and S among english speakers, probably due to the scale being originally devised in kyrillic script where C is equalled to roman script S.
• B and A Katod tubes are free to export and sell even outside of Russia while C require special permits and F are restricted to militsry and law enforcement use only. In spite of this both of the latter are available outside of Russia although F-grade tubes are very rare to find on the civilian market.
