Online prices range from approx USD 95 for a single tube to 950 or so for a pair depending on the brand etc. Nagra prices don't appear to be unreasonable .

Nagra VPA 845 retubing
Hi. I have a pair of Nagra VPA monoblocks with 845 tubes. I bought these used. When I contacted a local dealer I was told that I should only buy tubes from Nagra, because Nagra supposedly ensures that they are perfectly matched and are fully compatible with the amps (they costs 900 a pair!). Is this true, or is this a racket? Has anyone tried other matched 845 tubes than those sold by Nagra? If so, any preferences? Thanks
