SUN PSU capacitor maps

How about a 400-5330-03?
This is the one with the extra 100VAC output.
 
thanks for sharing.

i have that psu too, but its only 110v? can it be modded for 220v?
 
We just recapped @PascalP SUN PSU 400-5443, the values are a little bit different for his. Voltage for C11, C13, C15 and C16 are different (lower). The location of the hidden cap is C26. Also it has 3 2200uF 10V caps and 1 2200uF 16V cap like the 400-5443-02 revision.

Was a fun night, the Aoyue desolder station proved its value again ;)
Also while we where at it we replaced the PSU fan with a Noctua NF-A8-ULN and it is dead silent now, even on 12v without the additional adapter to lower the RPM's even further.
Highly recommended! :thumbsup:

so far i haven't done much to my sun PSU (i really should do that recap some time...) but i did replace the fan fan for a noctua - changeing the fans for anything arcade in a home environment is such an upgrade since i simply don't run the volume i would need to drown out these original fans....
 
Hi! :)

Does anyone know the value of the 2 Trimmer potentiometers to adjust +5v and +3.3V I would like to change them with stronger potentiometers and with an adjustment Shaft.
An idea ?

:thumbup:
 
Thank you nem :thumbup:

which model do you suggest with an included adjustment rod ?
 
I haven't looked. I think you might have problems finding ones that will go through the holes. You'll probably have to enlarge them.
 
Thanks for posting all this very helpful, especially the cap map. I just rebuilt and repaired a 400-5397-01 which seems to be the most common version. It was missing +5v after the recap turned out to be a bad resistor by the fan plug a 4.7k that had rusted in half. After replacing the resistor I wasn't able to adjust the 5v and it was too high, this was a bad pot. Both voltage control pots are 5mm 500 ohms. Finally I replaced the fan with a ARCTIC F8-80 mm which is cheap and also a perfect replacement much quieter than the original, you will have to splice in the old power plug though.
 
For the : 400-5397-01

1000uF 10V 10mm 1 C21
1000uF 16V 10mm 1 C21
 
The one I had was definitely 10V. Likely different batches.

You can always go higher voltage, just be mindful of physical size.
 
Yes i know, but if you can edit your post for 16v ;)

Hi @nem , thanks for this topic, it is currently helping a lot recapping my 400-5397-01.

I have a slight fitting issue with the C35 cap, the one directly next to the 5V and 3.3V cables.
13mm are fine for C28, C29, C31 and C32 for C35 I'd recommend 10mm. That's the diameter of the cap I pulled out of my PSU.

I'm not lecturing, just adding some experience.

Hi! :)

I have a question

I have a Sega model 3 power supply that I completely redone

I wanted to know if there was a Sonnor buzzer system included, because at one point I changed the system and I was at +5.25v 3 seconds and heard a buzzer sound.?(

I set the voltage to +5.1V and there was no longer this buzzer :?:

An idea?

:thumbup:
 
Definitely not on the PSU.

However, some boards have under and over voltage detection.

What board did you install?

Hi! :)

I installed a Namco system 12 which was a little sick, I'm trying to repair it , I powered it with the Power JVS connector
