Linn Sara product history
With my second pair of Saras came a number of photocopied sheets of info. Although it didn't say 'Linn' anywhere on them, it does
look like official Linn info. Below I've typed up the Sara history. The next few pages cover removal of drive units (these are
scanned at the moment, when I get a moment I'll try and type them up).

Mine are actually an active pair that the previous owner had paired with the passive crossover from
another (the earlier two-board version). This makes it simple to sketch out the circuit. The inductor
values are an average based on measurement with an LCR bridge.
Thanks to the good folks at Pink Fish, I've been able to update the crossover with the actual variant of Kef bass unit and later tweeter. My thanks to 'PL135' and 'RustyB' for the info (see this thread for further info).
