MIDI2CV8 printed-circuit-board, IC13 pins 7 and 8
An update has been made to the printed-circuit-boards for the MIDI2CV8 which changes the IC13 pin 7 Vee to be ground/circuit-common/0vdc instead of the negative supply. The printed-circuit trace to pin 7 has been cut. Thin, bare wire is added to link pins 7 and 8. When assembling the kit, insert the 4051 at this IC13 designation and solder the pins to include this wire link.
The change keeps certain lots of the part from running hot and/or getting some cross-talk between the channels it de-multiplexes.
