TRIODE, DUAL
6N23P is a direct replacement for 6DJ8/6922 tubes. Both Sovtek and Electro-Harmoinix 6922 are derivatives of Russian 6N23P. Most 6N23P found in USA are built at Reflektor factory in Saratov Russia.

We managed to find 6N23P built at Voskhod factory in Kaluga. These tubes feature an open plate box design, consistently made and measures closely.
