....a nos rectifier will make a very noticeable difference....the catch is that they are expensive ....i'm sure the Doc would love to put premium NOS tubes in his amps but for availability and price....
....he had a stance....major attitude...vibrato you coulda thrown a cat through....a little much....a little heavy....i guess the world just wasnn't ready....
As most have stated, the NOS can be counted on as being at or exceeding spec where as the current production are typically around 70% of spec. If the Doc went with NOS the price tag on the amps would rise considerably as per rectifier, the number of matched power tubes, and either key or all preamp tubes. The key I guess is buying from a reputable source that has put the tube through the testing paces such as GT

I quess the answer to your question is that on the whole, NOS rectifiers are more reliable than current production rectifier tubes. The current tubes are not made with the same grade of materials, and with the same quality control as NOS tubes were, and because of this, tend to fail more.
Sorry for the blanket answer, but tubes are tubes. There are no guarantees.
