Jim Welcome to time-nuts and you were indeed lucky to get a 5065. Lots of possible items. But the fact that the last line are all 0 may mean its as simple as the loop selector being open and not closed. Normally the control would tend to drift all the way over. On reset it goes all the way left and if it doesn't find the second harmonic it goes all the way to the right. Easy thought at least. Beyond that many possibilities for issues. After all they are old. Regards Paul WB8TSL
