Modifications for the BBC Model B and B+

On Issue 1, 2 & 3 boards a 470 PicoFarad capacitor should be fitted between
the emitter of Q9 (identified by an "e" next to one leg) and the base of Q7
(the central leg).

On Issue 4 and later, the capacitor is on board and can be connected simply
by fitting link 39 which may be found next to the modulator in the far right
hand corner of the PCB.
