[QuadList] Weekend Puzzle Picture

[Wayne Watson]

Yes, just when I think I know something the Quadlist humbles me. Now that I look more closely the AVR-1 buffer boards were larger and I do not think they had a separate plug in module. I happened to be on my computer when you posted and I got excited about getting my answer in. I clearly suffer from premature aguessulation.
I will stay tuned.

It has an Ampex look even if you did hide the seven digit 136xxxx-xx number (or was it 137xxxx-xx)
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.
Anyway this is my 4 micro seconds worth.
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 :)
