A company named Penta labs was selling tubes with old code
dates, with engraved serial numbers that happened to be the same
as those from bad batches of defective production run Eimac tubes.
Ameritron tried buying sample 3-500Z's from a company named
Penta labs, and the plate caps were glued on with rubber cement.
This may or may not be the same Penta.
