One other bit of help

[The Man Himself <altruist@shoko.calarts.edu>]

Yet another addendum, this one to the last post:

If anyone does indeed carry out the Echoplex signal decay test I
described, please try experimenting with different input knob levels; see
if the signal cuts off abruptly if the level is in fact too low. 

Gee, ain't it great to share one's moment of crisis with a bunch of 
strangers the world over?  ; - /

Your help is in fact greatly appreciated.  I'll try to leave you all 
alone for a little bit, now...
