Phono Stage Valves

Age doesn't matter, condition and test results do. Look at the glass base for smokey discolouration which can indicate amount of use. Personally if the bases are grey I avoid them, as issues like c/h leakage can start to show and are rarely (read never) disclosed. Given how long they will last you'd be better off getting clean examples and paying more, or go to a trustworthy dealer like Edicron or Wiwi tubes.

You should also look out for Fisher valves which were made by Telefunken and often get sold for less due to not being labelled as Telefunkens. The badge value as it were.
