Last post by NightWolve - 11/19/2025, 02:09 PM
I looked around for you via reverse Google-image searching and found that iFixRetro also bought one and did a capacitor replacement job on it! He made posts on X/Facebook/Instagram, so here ya go. I already asked him for you but you should too.

This is a high res photo, but overhead so not much help in identifying cap values unfortunately:

Console Repair/Mod Center / Duo Monitor - Capacitor C528 c...
Last post by Ptolomey I - 11/14/2025, 09:34 PM
Hi,
First of all, sorry for mostly posting requests for support on this forum.
I've acquired a non-functioning Duo Monitor that I'm trying to fix.
When I've opened the device I've found that unfortunately someone else has already had a go at trying to fix it by replacing some electrolytic caps with ceramic caps - not a good sign.
I have noticed that the capacitor C528 is missing.
I have tried to find info on the capacitor value online, but to no avail (console5 has a list of the electrolytic capacitors on the device, but some of them are missing, like C528 - link )
There is a post on a repair webpage by "grogory" ( link ) where he has some pictures of the disassembly. In a couple of them you can see the capacitor itself, but the values are unclear to me.
Here are some pics with the C528 cap highlighted:
I can see that the rated voltage is 50V, but I am in doubt if the capacitance is either 2.2uF or 22uF.
If you have any idea for the value of that capacitor, please let me know.
Thanks in advance!

Console Repair/Mod Center / Re: PC Engine ROM2AMP (AMP-30)...
Last post by Ptolomey I - 11/14/2025, 09:25 PM
In addition to the cap map, I want to say that if you have the loudspeakers that came with it and they don't sound good, there's a solution:
If you remove the metal mesh in front (a sharp object through it and some gentle leverage might do the trick) you will discover 4 screws that hold the 2 parts of the case together.
Inside, there is a standard 4-inch loudspeaker with a square support plate.
The speaker itself has 8 ohms and rated at 15W max
Space in the case is relatively tight: the loudspeaker is 6cm tall, and I'm not sure if any size bigger than that might fit
In any case it should be easy to find a replacement, de-solder, and re-solder the new part
Hope it helps!

Console Repair/Mod Center / PC Engine ROM2AMP (AMP-30) Cap...
Last post by Ptolomey I - 10/24/2025, 10:17 PM
Hi,
I recently got a PC Engine ROM2AMP accessory as I have seen it produces a nice sound, and I like the design a lot!
I am preventively replacing the caps, so I have created a capacitor chart.
It is based on the image uploaded by user thearthur777 on reddit ( https://www.reddit.com/r/TurboGrafx/comments/1e8uclk/pc_engine_amp30_capacitor_replacement_chart/ )
There is a discrepancy on one capacitor between their capacitor list and my unit.
Maybe my board is a different revision, but given the low sales of this accessory I doubt that there's more than one revision. So, I think the best would be for everyone to verify all their cap values before any de-soldering.
Capacitor map and table:
Then, the usual disclaimer that I am not responsible of any possible negative impact on your console following the information shared.
And finally, if there is any error, please let me know for correction.

Hi,
Keeping my promise from the previous thread, I am posting the capacitor maps from my PC-FX
Link to my previous post: https://www.pcengine-fx.com/forums/index.php?msg=522315
You will find board sketches to identify capacitors, then a table with their values.
PSU board:
PWA board:
PWH board:
Then, the usual disclamer that I am not respponsible of any possible negative imapct on your console following the information shared.

Makes sense they'd want you to have a sample to entice you to subscribe. 
After going on a bit of a search to see if anything could jog my memory, I found someone selling a TG16 in box and they included a pic of the contents and it seems this brochure did come inside the box, along with the poster.

Last post by NightWolve - 09/19/2025, 12:15 PMWow, I can't believe this post motivated someone to register and reply to it!
Yeah, hard to believe but I knew about that link because a veteran localizer shared it with me a long time ago given his English localization projects!!! The company removed the DRM protection from the 2000's era and let the world have the games for free, yeah, it's surprising! He also has a sitting nearly finished Magna Carta localization project but wanted help for final finishing touches so it's not getting released until then or maybe never unfortunately...
You must be pretty old skool to remember Heroine Anthem and the Chinese RPG PC era! Anyway, welcome, I know I've seen your name before, it's familiar!
EDIT: I looked at my old RIGG PC Engine forum offline copy, I found a member Gilgamesch / rocco.hilton (at) gmx, was that you or coincidence ?? Were you a member 20 years ago ??

Last post by Gilgamesh - 09/19/2025, 07:39 AMI don't know if you're aware of that, but it's worth mentioning that WindThunder has made the first 2 Heroine Anthem games available for free download from their official website:
https://www.heroineanthem.com/vocal_version/en-US/index.html
As far as I know, a Simplified Chinese version was also available but now it seems your best bet would be to check if it was saved in the Wayback Machine.
