Dave: I will try to verify the part number when I get home this evening.
As for now, the Tektronix Component Number is A16, and the Tektronix Part
Number is 670-4769-01.? I need a fully populated Vertical Channel Switch
circuit board for the 7104 oscilloscope.? Thank you for your assistance in
this matter.

Hi Gary,
I looked the PCB up in the 7104 manual and then checked my stash of
boards, and I don't see anything that comes close. I did have a full set
from a 7104 that was taken out out by a forklift (upper left side hit), but
I don't see any of the lower section items, so I may have sold the entire
lower half at some point. I do have a few other hulks, but they are
"functional", so I don't want to part one out.
Sorry! I was hoping...

Dave: Thanx for looking.? If you ever come across a Vertical Switch circuit
board from a 7104, please contact me.? I suspect there are few individual
boards just laying around.? The board makes use of a custom Tektronix
thin-film hybrid U668 #155-0173-00 which is not 2nd-sourced.
