[Milsurplus] Radioactive OA2 tubes?

[Mack Rogers]

Excuse me gents, radio station N4VGB (good on all callsign address databases) is the official U.S. Government EPA approved disposal site for those dangerous radioactive vacuum tubes of all types. In hopes of ridding the earth of all these dangerous radioactive devices, we will even reimburse the shipping/postage costs for all dangerous vacuum tubes shipped to my address. Congress may end the funding for this program at any moment, so please hurry with those tube shipments. It is rumored that severe EPA fines may be levied against all who refuse to voluntarily dispose of all their vacuum tubes in the proper manner soon.

Thanks in advance for your cooperation.

N4VGB
