My 5kVa Topaz will arrive tomorrow. It’s untested so hopefully it’s not a dud but the price was to good to pass up. It list as weighing north of 100 lbs so it’s probably going to stay on a furniture dolly so it’s easy to move for wiring and testing. I’ll edit this post with pics tomorrow night.

Edit: Here it is next to one of my 2.4kVa units. Sorry for the bad pics. I just got home and it’s midnight here.

It works! I hooked up a cord to it it and I get 115v in and 119.6v out. Well worth every penny!

@oneguy Can we get a pic of the beast!? I have a 91001-31 on it's way ^_^. I'm afraid of the hum though... Maybe put it inside of some type of box? I may have to make a DIY box of some sort if the hum is too bad. New Topaz will be dedicated to my PC for surge protection and hopefully some SQ benefit. We'll see.

Of the units I have, the -12 or -11 units have a hum/buzz and the -32 -31 units are silent.

Did you get it off ebay just recently? I saw a 91001-31 all wired up with a plug and 4 outlet box, nice unit.

gz!

Both of my -32 2.4 kva units have a slight hum that you can’t hear any further than 3ft away in a completely silent room. If there is anything blocking that “line of sight” the it drops significantly. I have never run my -32 500 unit by itself so I can’t comment.

EDIT: If there is nothing between the -31 125 va transformers and my ears I can begin to faintly hear them at 2 ft. If obstruct that direct “line of sight” with something as simple as cardboard it drops down to about 10 in.

Here’s the photo of it next to a 2.4 kva and 125 va unit for reference.

That is a behemoth. WOW that is a massive transformer! I wonder how hot all of those things get. My setup with all of the equipment firing it gets hot in my room, especially when im pushing my video card for gaming haha.

@Zenvota
When it comes to replacing the oil capacitor would you deem it necessary or... I really would like to replace my receptacle but I'm not sure if I should replace the cap too and what specifications to look out for in a replacement. I'm all in for do it right the first time.

I dont know Dx I need to look into it as well. I would imagine if its not leaking its ok to leave it, if its old and ineffective it just won't do anything, its meant to filter some extra traverse mode noise. Should be very simple to remove though.

0623191245.jpg oyaide-r1.jpg I noticed on the stock receptacle that there are 4 input posts per side, and the Oyaide R1 only has 2 inputs per side. Because of the way this Topaz is wired you can see the neutral has a ground going into it as well.

If i am to wire this to work the R1 would I need to terminate the neutral and ground together into one crimp or is this not advisable?

If you connect ground and neutral on the output make sure you add a gfci between the receptacle and anything you're plugging into the topaz. If you don't connect the ground and neutral on the output then it's floating and you don't need to do anything else.

Ah! So it's the output not input. Doh! Learned something new hehe.

I may consider the Furutech GTX or the Maestro in this case. I'm afraid implementing a GFCI for the R1 is beyond my technical ability and understanding.

Using a gfci is for grounding the neutral not for using the r1
