See what the core is worth to a rebuilder to set the minimum. Its a very
common tube over here and $200-300 is typical for a pull as there is a
minimal market for used ones except CB and hams.

Good sockets can easily be twice the tube as commercial stations also bust
them up on a regular basis and need one pronto without going into hock from
Richardson Bandits, Ltd.
