Stanley,
Hi! I can send a couple SMB if you would like?
Have your run the TED for a week?
When the lamp oven is warmed up did you happen to observe the lamp color by pulling the lamp assy out while still hot? I'm concerned about the color of your cold lamp in the picture.
Did you measure the lamp ovens temperature after the repair? (Did you use the original thermistor?)
If your 60Mhz looks OK now can you see a signal yet when you adjust the Quartz fine frequency across resonance at A7TP2?
What is the frequency and amplitude of the synthesizer output?
If you measure with an ohmmeter set to test semiconductor junctions both ways the 60Mhz input jack to the optical unit do you show a junction in one of the directions?
![Phew :phew:](https://www.eevblog.com/forum/Smileys/default/phew.gif)
If still no A7 TP2 signal we have to try testing the optical unit via an external signal.
Did you dig up the HP 3325B?
What synthesizer thumbwheel setting as shown on the optical unit label?
I'll need to try this on the unit I have on the bench and once I get the details straight I'll post instructions.
Cheers,
Corby
