Notations

There are several circuit baords added above the main board for added features. One of these is what appears to be a small audio board mounted above the 2SC827 Regulator transistor area. It has two audio circuits for the left and right channel for the MP3 player.

The parts for the 4008 divider chips etc have all been removed in lieu of the new computer control board near the Channel Selector.
