My G91A became totally unused since I turned to SLS. Now I decide to give it a play, I am going to make an external LPSU for it. Here is the front panel of the device which it may look. ![[Linked Image]](https://www.meridianunplugged.com/ubbthreads/gallery/16/full/2027.jpg) or ![[Linked Image]](https://www.meridianunplugged.com/ubbthreads/gallery/16/full/2028.jpg) Any ideas or suggestions are welcome.

Nice looks, but I miss the "why" in your post.

Good question, because I just replaced a new switch mode power supply for my G91 month ago.
I don't even really care about the sound improvement it may do, just for fun!!

Have to say the progress was little bit slower than I thought. **update** Front panel and custom transformer are ready,waitting for capacitor from us supplier and glass top cover! ![[Linked Image]](https://www.meridianunplugged.com/ubbthreads/gallery/16/full/2037.jpg) ![[Linked Image]](https://www.meridianunplugged.com/ubbthreads/gallery/16/full/2038.jpg)

Nice. Is that your own design or general market?
Would be interesting if you measure the performance vs the standard one.
Cheers!

Thanks, I finally got someones attention.
No, I tried once, and ended up blowing up both my 861s fuse and the linear power.
This time I have my friend to make it, I just provide the data. Now we are waiting the custom glass top cover to complete the job.

Where did you get the specs from? Does this have voltage regulation built in or is it standard rectification and smoothing caps?

The only spec I gave to my friend was the spec of original switch power supply.

Hi
It's interesting. I want to make one for my G98. Do you know if it is exactly the same as G91?
Please let us know the performance after you have tested.
Thanks

I am not sure they are same. I think I wont comment for the performance, too objective, especially for my own design. Actually now I only use Sooloos.
