Did a major breakthrough!
Obviously it was my fault, by mistake i swapped two connectors.
My luck is that the power board has some safety elements.
OK, now with the connectors in correct position
I have 8.5 and 17 volts on the outputs.

Fellow time-nuts,
I received the OSA 8607 Family End of Life Notification from ADVA
Oscilloquartz.
This is the last BVA from OSA. It comes as no surprise, especially since
they dropped their other OCXO business, but this was their crown jewel.
Cheers,

Ohhh that hurts and you were lucky. I always mark connectors for that exact
reason. I was going to download the pictures but it kept trying to download
some executable. So will not be able to look at your pictures.

Replacing the caps could have increased voltages and exposed a fault that
caused the caps to fail...
As always step 1 - check voltages/regulators. Remove bridging components
(diodes, power resistors) if necessary to stop the smoke and trace the
circuit as any number of components could have
yes I got these executable too, and therefore did not continued

I forgot to tell you to uncheck the download manager thing, that's why it is
downloading .exe.
Anyway, i ran some test today, i unplugged the high voltage driver and found
out that instead of 10 volts on one output i now have 13-15 volts, which means
that either it is a bad filter, or the pwm
I've done some more work on the code, mostly in the area of health
monitoring -- it's able to look at whether the GPS is locked, whether
the Rb is locked, and whether the PLL has a good capture, and decide
accordingly whether to enable 1PPS and whether to report a good lock
on NTP. It will
No web page, but a little description here. It has changed quite a bit from
the original description. Now uses TAOS color sensors. Suppors Melexis IR
thermometer chips. Has 16 bit A/Ds. Processor is an ATMEGA 1284. The control
program is based on Lady Heather. Besides LEDs it can

A short update on NAA as some sort of reference.
Have completed a simple direct conversion circuit using a NE612. A few
minor changes because the system only needs 100 Hz or less. It is
essentially this circuit.
