<DIV dir=ltr><FONT color=#000000 size=2 face=Tahoma>It has an Ampex look even
if you did hide the seven digit 136xxxx-xx number (or was it
137xxxx-xx)</FONT></DIV>
<DIV dir=ltr><FONT size=2 face=tahoma>For time base correction Ampex used
switched (a binary sort of thing) delay lines in the AVR-1 and ACR-25 buffer.
The delays were based on switched in glass delay lines (with appropriate
mod-demod). The "Corning" part is what leads me to this guess. The handle is
also a clue. However from past experience with this expert group some one will
step forward with exactly what amount of delay this board has and them my
friend Bill Carpenter will step in with a great stry about it. I think
they had delays like 2usec and 4 and 8 sort of thing.</FONT></DIV>
<DIV dir=ltr><FONT size=2 face=tahoma>Anyway this is my 4 micro seconds
worth.</FONT></DIV>
<DIV dir=ltr><FONT size=2 face=tahoma>I hope I do not win because then
I might have to put up a picture and the one I have no one may ever
figure out :) </FONT></DIV>
