Harpsichord tuning

John,

First you need to uncouple the manuals, turn off all the registers 
except the 8 foot register that plucks closest to the tail of the 
harpsichord (farthest away from the tuning pins) and tune that 
register to your ETD. Then you tune the other registers one by one to 
the register you tuned first by setting up either the coupler or 
register levers so that your initially tuned register and the one you 
are tuning pluck at the same time. Tune them as beatless unisons (or 
octaves, in the case of a 4 foot register). If this is a Sperrhakke 
or Neupert or another of those German production monstrosities with 
the 16 foot register, tune that one last the same way.
