Good day guys!
Does the 3394B has the same CRT as the 3370B? I would like to replace the CRT in a 3394B.
I found a PM3394B here in Hungary for around 190USD. Badly yellowed (Hydrogen Peroxide & UV might help), needs calibration (cursors are vertically off), and likely changing of electrolytic capacitors required (slightly blurred screen, cannot focus well). Calibration runs without problem, however after a hour some traces shifts by about 1mm from GND. Self test passes. It has GPIB, Math+ and Extended Memory options, newest firmware. No optional BNCs at the back.
I think the price is not bad, but the screen has a burn-in! This burn (at least for me) is serious as it can be seen clearly. It's about 2mm wide horizontal line exactly at the center line. It's probably a device that was used by careless technicians 0-24 in industry with high brightness in digital mode.
Thanks in advance for your answers!
