IBX100 sound components - revision A, again...

[Mark Leman]

More work, I've put all the component designators (IC1,C1,R1... etc) on the
schematic at
http://www.crundalls.demon.co.uk/mark/bush_internet_tv/ibx101_audio.pdf and
beep-ed all the connections through, now I need to add the J-K flip-flop and
trace that bit out and back to the PS7500. Then for all the component values
from Ralph's table and I'll be ready to solder :-)
