Hello!

having a small problem with the laser stated in the title, I can't
seem to get any discharge in the tube and the Cd and He heaters dont
seem to be coming on ( shown by the LEDs on the front of the PSU ).the
power on LED lights, and the head gets power ( cathode lit and
internal PSU on ). I think it may be an interlock thats not being
satisfied and I think I have found that interlock. There are two
yellow wires with a connector on the end coming off of the low voltage
connection which I think are the interlock leads, but since I've never
used an Omni 100 PSU and 74 series head I am not sure. Is there anyone
around here who happens to have used these and knows what the problem
could be ?

Many regards,

Adam
