Will this amp work when you take the audio signal after the volumen wheel and before it goes to the GBC amp? Then you should have a cleaner signal like the cleanamp pro it does.
So just did this mod, went from too quiet to too loud. Can’t go past 1/4 volume now with out it being blisteringly loud. Should I put a resistor or something?
I've bought some of these along with a GBAmp3. Looking forward to comparing them! Gonna try sticking them in GBAs. Edit: If you want to install one of these in a GBA, a quick warning that it isn't as friendly as the other Gameboys. Only do it if you're confident in your soldering skills because it's quite a bit less space and more complicated than other Gameboy consoles. You have to lift one of the pins in a chip and bridge two tiny points with wires. Doesn't sound like much, but it's a pain and I'm still trying to get it just right.
Will do! I'll be getting on that next week, the GBAmp3 board is already here but the ones that you used will take a little while longer for shipping. Just gonna put together the GBAmp3 board for now.
AFAIK the AGB AMP in the GBA is a DAC, so you cant avoid having it use power. The PAM could be used to increase the volume or drive a higher resistance speaker. If you want the PAM to reduce noise, then maybe this fix can help instead gbatemp.net/threads/gba-speaker-noise-fixed.450093
Tom Clark you could probably add a 100uf cap to help decouple any noise from the supply. Unless it's generated within the CPU then there isn't much you can do. I've noticed some GBCs are just quieter and some noisier. A dirty power switch definitely makes it worse
I just picked up my first GBC a few days ago. I was in college when they came out and wasn’t really playing too many games at the time. I also have a GBP backlit (waiting for my kitsch-bent Bivert to arrive). When I turned on the GBC I could barely hear anything, thought the potentiometer was maybe dirty. Nope, so I ordered a new speaker....then I saw this video. I will still replace it since I paid for the speaker but also ordered one of these chips (had to buy 3). Gonna try as soon as it arrives. Maybe I will just go ahead and clean out the power switch too.
This probably won't be read but is this amplifier just as good as any other gameboy specific amplifier? I suspected their prices were inflated but I don't know if the extra price is worth getting gameboy specific amps instead of this one
Question, I have this mod installed. It works great, but with a funnyplaying IPS Q5 v2 mod installed, the screen introduces noise into the circuit, I've tried also adding the power filtering capacitor mod, but it seems to have not had much of an affect. Anything else I can try to lessen the effect of the screen causing noise? The noise changes based off what is currently on screen, and I assume it's due to the screen tapping power from the switch by being soldered to the C pin.
It may be your switch needs cleaning. You could temporarily bypass the switch to see if that changes the noise, if it does you've found the culprit. If not, there may be too much load on the stock power supply in the GBC with all the mods
@rey olmilio probably an issue with the LCD mod, back light may pull most of the power but it is one of those drop in screens. Shouldn't have caused too much of an issue but I just realized that if the Gameboy is native 5v nothing stopping me from dropping in a rechargeable battery and circuit.
Ruh roh. I may have underestimated how easy this would be to do. I installed a GBAmp3 without too much problem using the less noise instructions and it works a pretty good treat. I even replaced the speaker with a DS Lite Speaker and it's got a pretty lovely increase in clarity. Now when I tried installed this board through what I hoped would be the same instructions... Nuh uh. The pads on the PAM8403 are a little different, and I'm not entirely sure how. Went on a hope and a prayer and proceeded anyways since I figured I could just take it out if anything went wrong. Nope. Even after removal and soldering that lifted pin back on, the GBA won't power on anymore. Bother. Best left to someone who actually knows what they're doing, I.E. not a person who's only competent at following instructionals.
gundam126 yikes! I wonder what went wrong? I'll dig out a GBA and have a crack at it too. I wouldn't have thought the GBA would be too different, I guess it is!
Yes, the speaker will still shut off if you plug in headphones. I jist tested it to confirm on the one I've modded. The amp just sits between the motherboard and the speaker, so this tutorial doesn't alter any part of that circuit.
I did this a while back, and it works great except the GBC crashes when headphones are plugged in or out while it's on. Any thoughts on why this could happen?
Hackintosh add a large cap across the Pam modules supply pins. It'll be the DC bypass cap discharging and pushing overcurrent into the speaker resetting the GBC.
Hackintosh 6v or higher, and as many uF as you can fit. Aim for 100uF as a minimum. The idea is to give the amp extra available currently to stop it pulling down the system voltage and triggering a reset
Finally got around to doing this i hadnt opened my gbc since i did the backlight mod. did this + a rechargeable mod at the same time I also added a power led. I had the same issue with flickering and cleaning the switch didnt fix it but it only happens while plugged into ac
*Better tutorial on reddit for those getting static issues **imgur.com/gallery/Dq8C7wM*
HXJ8002 Amp look it up on Aliexpress
Just use a ds lite speaker... Easy and sounds better than the original one
*Will this work with the new Freckle Shack mod?*
im using it with the mcwill lcd mod
I have the same question =/

Same, help? :c
you need to get a new 1W speaker for better result

gundam126 post your findings when you gather your results!

u know we all are waiting your findings, right? =)
Dude! Where are u!?
do you have a little schematics for gameboy classic using this chip PAM8403?
I tried the same on my gbc and do the switch cleaning but still that noise from the speaker came out... any idea what it cause?
PAM8403 Class D Audio Amplifier 5V
Im getting a lot of static noise coming from the speaker after this mod. Any idea what could be causing it? I've tried using a different speaker
Tom Clark if your GBC was noisy before the mod, it'll amplify this noise. Any other mods? What version is your motherboard?
No other mods, version 05. I think its likely amplifying existing noise. I have other, unmodded gbc's that make the same noise but much quieter
Tom Clark you could probably add a 100uf cap to help decouple any noise from the supply. Unless it's generated within the CPU then there isn't much you can do. I've noticed some GBCs are just quieter and some noisier. A dirty power switch definitely makes it worse
Where would we fit the capacitor on this any schematics ?
That sucks man, I have 2 amps on some gameboy colors and I don't get any kind of static. Did you figure out what the problem was?
Would this amplify the dmg gameboy
Yes, would you like me to post a link to a guide, I got 5 of the PAM8403 amps, and I have installed one in each gameboy I have
What size wires are you using on the amp?
I used AWG 28-30... Works great, but man is it loud 👍
Fantastic guide my gameboy is LOUD and I love it
could you please make a video mod sound like this for gba fat?

sorry for the late reply, i suspect the gb specific ones are easier to install, the audio quality will be much the same

wow thanks it is so much louder
Could this work with a GBA?
It's an amplifier.
Having issues with this, I have a back light mod and with this installed the gameboy does not power on.
@rey olmilio probably an issue with the LCD mod, back light may pull most of the power but it is one of those drop in screens. Shouldn't have caused too much of an issue but I just realized that if the Gameboy is native 5v nothing stopping me from dropping in a rechargeable battery and circuit.
The pam8403 works great with 3v max voltage it's 5volts
Will this work with the Pro Sound mod?
I noticed that low power batteries make the sound go weird or no sound at all, probably normal right?
Yes, that is normal
@@ellaquin Thanks

@@chrissyfrett9228 Just wire a 10k ohm resistor to the SD pad on the amp, to pin 5 of the headphone jack.

Awesome
Nice i'll definitely be doing this

Can you make a video of it in an original DMG Gameboy? 🤔
I can show you a guide if you want
@@ellaquin i figured it out the same day I commented. I can make a tutorial if it's needed.
When will the ElCheapoSD v2.0 be available again benn?
David Kerekes soon, maybe a few days
Thank you sir.
