For my V7.5, I have to use Nautel's exchange program. Cost about $900 each. I took one apart to see what I could do and while I think I may have been able to find and correct at least part of the problem, if the chip(s) that control the frequency and PWM and voltage regulation are bad, I wasn't sure I would find them. It looked like a time-consuming shot in the dark so put it back together and shipped it off to Nautel.

Nautel may not repair them, at least that’s my experience with Nautel VS series.   They purchase the supplies from a third party.   Many switching supply modules are made by third parties.

 

For Nautel VS series you can have supplies repaired by CEI, phone 416-630-8108.   Don’t know about the 7.5LT.

Tim:

 

Why, don't you want to send the supplies into Nautel?
