Hi! Awesome video, thank you for posting. Do you have any suggestions for the same model power functions fine, but the meter on the front is stuck somewhere between 8-10v and 10-12 amps. Needless to say on meter moves slightly when adjusting voltage, or drawing amperage. Meter returns to to all the way left resting position when off. I metered voltage, and it’s outputting just fine. Thank you in advance!
Mine is a DM-330MVT - uses C3306 transistors instead of mosfets but don't they work the same here? Mine had low voltage (2V) and no fuse blowing or protection faults. Replaced the transistors with the mosfets you used and now it lights up the protection light. How should the NPN's check out? I will put them back and start troubleshooting again. I read that these are common problems so I jumped the gun but need some help!

I have to without a doubt ditto Marty’s comments! 😊🙏

great video. Can you say what near equivalent mosfet you used please.
Thank you for watching. The replacement MOSFET used is a 47N65E.
Excellent - I have the same issue - 2 dead Mosfets. Thank you
47N65E plus the rectifier worked fine for me in a DM330MW 2 - so thanks again for your video.
