From: [email protected] RT-70B came in with Change 2 dated 4 April 1958 to =
the TM 11-290 you have.  Appears that there was only the one Order, as =
Changes 3 and 4 don't mention any later ones.

It says that RT-70B is identical to RT-70A except that resistors have =
higher max temp rating, some capacitors have lower positive tolerance =
temperature coefficient and some caps have decreased value tolerances.

The only other thing mentioned is to change C-14 to C-41 on Fig. 47.
