K2 Z10000 Buffer amp

[g0who]

Inputting 10MHz to K2 but no IF on rear BNC. Measured signal level from
K2 at input of Z10000 board is 35mV, on U901 pin 3 level is 10mV, but
'scope shows no signal at pin 6. Connecting K2 IF op to K3 ae input a
very weak oscillation can be heard.
Suspect  AD8007 IC has gone, but what signal level should be expected at
Z10000 output?
