Actually, Namesake-san, the thing reads "Can be changed as easily as a radio
tube"  However, if you want to do it the other way around, this can be
accomplished by means of the following procedure:

1.  Unplug ballast tube from Radio #1 carefully, avoiding excess wiggling
and jiggling and set tube aside carefully in a safe place..
2.  Remove Radio #1 and set aside (for shipment approved repository -- 
address to be supplied later)
3.  Move Radio #2 (w/o ballast tube) exactly into position previously
occupied by Radio #1.  (Radio #2 must be a compatible model, such as
R-390/URR, R-390A/URR, R-391/URR, etc, -- not a Zenith Transoceanic which
requires a 50A1 ballast tube, unless Radio #1 is a Zenith H-500, x-600,
R-520, of course.)
4.  Lower ballast tube removed in step one into position in Radio #2, being
careful to orient pins properly and gently press downward to install into
socket.
5.  Congratulations!  You have now successfully changed a tube radio.
