Fisher 500c rebuild
#16

The New Sensor import tubes are just rebranded Russian made tubes, although they are new production, they are all made in Saratov in the same plant that made Reflektor tubes in the Soviet era. So the way to save money is to find the number of the equivalent Soviet type, such as a 6P3 for example, and buy a surplus mil spec example from Russia, Ukraine, or a former Warsaw pact country, I've never bothered since I have lots of good used North American tubes for personal repair work, but may if I decide to build a new amp or rebuild a friend's amp that has bad tubes.
Regards
Arran
