You are looking at a very nice, strong very well matched pair of Sylvania USA made black plate 5V3 full wave rectifier tubes. One is labelled for Zenith but is Sylvania made. The bases are tight and there are no cracks, chips or loose particles in the tubes. They are in excellent condition and measure as strong and very closely matched between plates Tube 1 - 1000 & 1000. Tube 2- 1000 & 1000. This is a very good, strong perfectly matched pair. Nominal replacement measure for the 5V3 is 650.

The minimum shipping weight is 500gm, I pack tubes very well and I have only ever had one problem with damaged tubes in over 10,000 sales. There is a very small handling charge to cover packaging and handling. I do not profit from shipping and I wish I could charge less. I am a registered business and pay all the appropriate Australian taxes including 10% GST.
