Fairlight-CMI

Hi Arron.

To replace the analogue supply fuses in a "standard" series III, you do indeed need to remove the bottom cover. Just turn the machine upside down and remove the 10 x screws, underneath you'll find the (from memory) CMI-310 board which as a row of fuses, all labelled. This is also a good time to clean the air filters in the base..

What do you mean "superhuman" strength to turn the machine upside down ??? I have to carry CMIs up three flights of stairs on my own, to get them in my workroom !!  

Regards,

Peter Wielk
