Creating schematic for the nanao MS2930

[cruzlink2]

Hello,
I did not receive any feedback with the KiCad files only. I just added the PDF.
Enjoy.

thanks for all your hard work Franck

I need to be more specific on a comment from the schematic

It's on the DC power , TP6 or C972
I need the exact measures for each mode (16/24/31)Khz
The actual info is from MS29131 service guide.

I totally forget to correct this with the functional chassis (now gone).

Can someone measure it for me please ?

I will do this soon for you as well as send some cash along through the coffee link! Your schematics work has been very helpful in troubleshooting the dozens of chassis I am dealing with all the time

Last fault I relatively quickly found (with my schematic)

-working ok in 16/24 KHz
-going to protection 5 seconds after switching to 31Khz

I was Q507 dead open. It caused output 6 of U971 slowly rising.

But at that time, it didn't know the exact B+ to expect (I still don't), I measured 112v
Hence the ask for info (thank Kevinddr...).

​

Please relate your fixes here !

Great work! I wish I had a ms2930 so I could help you finalize this project.
