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:

Item	Capacitance (uF)	Voltage (V)
C103	2,2	50
C104	2,2	50
C107	0,33	50
C108	0,33	50

C110	47	50
C111	100	10

C301	10	50
C302	10	50
C305	10	50

Hi,

Keeping my promise from the previous thread, I am posting the capacitor maps from my PC-FX

You will find board sketches to identify capacitors, then a table with their values.

Ah, nice. I remember the manual at least. I'll have to check what TurboPlay/TurboForce magazines I have some time.

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.

Wow, 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 ??

I 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.

Hm, I think a magazine issue was included inside my Turbo Duo box, but it wasn't that one with Keith Courage on the cover, it was the one below.

And while I won a TurboGrafx-16 (and lost the box, the console broke, I threw it away), I don't remember a free magazine inside the box for sure, though it makes sense they wanted you to have an issue so you could potentially subscribe for others.

Does anyone remember if this was included with the purchase of a new TG? I swear I remember this magazine, but I clearly never subscribed since I got my TG when I was 7.

Glad we could help!

For capacitor info, check console5 too since they sell capacitor kits.
