<div dir="ltr"><font face="Tahoma" color="#000000" size="2">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 face="tahoma" size="2">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>
