The Winged C 6N1P is similar to the 6DJ8 except that the 6N1P has a higher heater current. May be a suitable replacement for 6DJ8 / 6922 variants. ? Please check with the manufacturer before doing so.
These tubes were purchased from the North American SED distributor ten plus years ago. This tube does appear to be manufactured by Voskhod. As far as I'm aware, SED never manufactured a 6N1P.
