Yes, I did. If I don¡¯t, it comes up with an error 264. By doing the calibration, I am only left with an error 256. I then adjust the flatness pot and can get it to ¡°0¡± PASS maybe 9 seconds out of 10 and then it fails once and then passes again and again and occasionally fails again. When I do the self test, it FAILS every time with 256

This guy has 3 videos in a series which were helpful. He replaced the FETS and the problem was eliminated. He seems to be having the same issue as me. I just don¡¯t know which FETS he used and Keysight can¡¯t tell me

Hi Craig,
Debugging the actual issue is more fun and I am sure Dave would agree but the transistor can be found by searching Keysight:
Database says it is a J304. Mouser in US has them, I don't know about the distributors in Australia.
