A suggestion for anyone planning to copy this - get 8 fets from one batch, so 
the gate thresholds are likely to be close together. IR specify a range of 
2-4V so a mix could end up with only some being biassed, and the others being 
non-linear. After a blowup, replace the whole lot to avoid mixing batches 
(hardly expensive!).
