Two questions for you guys:
1. If the 82 connecting block was designed to make the 4A a "plug 'n' play" device, what was the Model 80 control unit designed to do?

2. As a corollary to the above, if you have a 680 transmitter that has had the amp plug cut off, is there any way to hard wire it to an 82 connecting block? I notice that there are a lot of screw terminal there besides the two a.c. terminals for the 85 transformer input. Could any of these be used for the 680? Also I have a 683 that has all spade tip connections. Would the Model 80 be used for this or the 82?
