Hi, everyone. Just wanted to ask for some guidance on a newly bought source four. How hard is it to 1) turn the inner knob for flat field adjustment, and 2) to remove the lamp from the socket?
Even the most minor turn on the knob is next to impossible, and it could only turn about 20 degrees maximum (and with the most amount of effort). Do I have a defective unit? As to removing the lamp from the socket, is it normal for a new unit for it to be so tight? It took me a good 15 minutes to do it, trying both a gentle and a robust approach. Could someone help please?
Many thanks,
J
