Subject: Master 128 questions

1) I have a Master ET which is not producing any sound although it is working 
normally in every other way. Even the start up sounds don't happen although I 
sometimes get a quick bust of static from the speaker when I do a 'R' switch 
on. I've plugged in a known good speaker and it still does not work. Has 
anyone got any tips on what the problem might be? Is there a volume control 
somewhere on the motherboard? What does VC1 do and is it related to sound?

2) A standard M128 this time. This one has three small batteries fitted into 
the area in the cartridge/speaker assembly with contacts and 2 wires running 
back to the battery plug near the power supply. The wires do not have the 
diode and resistor on them and I have not seen this type of assembly before.
Is this an infamous exploding batteries set up or something else? It's an 
issue 1 machine and the modulator is dated 8435 but the keyboard and PSU are 
dated 86.

Thanks,

Mike.
