Two versions of Yamaha C-2

There are actually two different versions of C-2. An earlier version of it (that is maybe/maybe not different internally) uses a rotary for muting next the the volume/balance control. I presume it is earlier than the C-2 documented here on this page which has the toggle next to the volume/balance (characteristic for the others in the series, also. Note the C-2a curcuit is very different from the two versions of C-2.
