Title: Twin Famicom or AV Famicom
Post by: Terpor on June 07, 2012, 04:15:51 am
Is the AV Famicom really worth it? I already have a Twin Famicom and i really hate the short controller cables, and that the audio is a bit muffled compared to the NES. I'm planning to sell my Twin Famicom, or trade it to the AV Famicom, but is there that much of a difference between AV Famicom, or Twin Famicom.

The AV famicom is the best model.....for modding.  I have nothing but love for the av famicom (I own 3 myself).  I also have a sharp twin famicom and I love that system too but the muffled audio sucks.  Even for composite video the av famicom is perfect looking.  The only complaint I can think of about the un-modified av famicom is mixing in carts with upgraded audio chips is lacking....bass.  The upgrade kits I use fix the audio (and actually make it better sounding than any stock console) but unfortunately the kit costs 150$ because it's meant to upgrade a whole lot more.  Also the audio circuit only sounds perfect on the av famicom which is another downside.

muffled sound is just one capacitor.

As about AV grey one - it's a bit fluffy, classic one more robust. Twin? mmm There is profit, when it&s turbo twin


really?  Which cap?

There's a 0.022 uF cap located between the video and audio jacks. Ace discovered this on Sega-16, just snip it off and the audio becomes crystal clear. It should be marked as C205 on the power board.

Can you post a link to the post, or do you have any pictures of this component? So i just remove it, and i get better audio?

It seems to me there ought to be a reason why that cap is there

According to the link previously posted by 2A03 (See http://tinyurl.com/7oxyydw (http://tinyurl.com/7oxyydw)) You'll have to change a resistor out on the disk side of the system to normalize the sound between disk and cart modes.

It's a low-pass filter for audio so all it does is filter out some of the higher frequencies in the audio (hence the name), removing it has absolutely no harmful effects. I removed the one in my Turbo Twin a month ago and it's still working perfectly fine.

Okay, did you also change a resistor out on the disk side of the system?  :blinky:

I didn't do it with mine, you don't have to do it alongside the filter removal.

I have never owned a Twin Famicom but I do own a AV Famicom and it's a spectacular little system.

Hello,

Here are some pics of my Famicom AV and Twin 505 : http://jomay.free.fr/Famicom_AV_Twin_505/
It's a pain in the ass to take good pics. I would say that the quality is the same, but the Twin outputs brighter video.
I have moved everything in my garage and yet didn't find out the TV remote control, so I wasn't able to adjust brightness/contrast/colour to verify that the quality is really the same.

It the Famicom extra controller port supposed to feel loose, and i think my controller might be broken "or i think so"

I used my Sansui Joycard  on TW and sometimes the buttons don't feel that responsie, and controller was cleaned when i bought it.
