[sdiy] Hammond Vibrato Scanner

[David Brown]

I fed my synth output to it which is 10 volts pk-pk and the output 
from the scanner seemed to be a typical line-level -10dB output  I 
didn't measure it but just plugged it into my preamp and it sounded 
about right.  Based on that I would think you would want gain of 
~15X.  I would probably add the gain going to the delay line so the 
output of the scanner is about the right level and then just buffer it.
