Do you mind posting what you charged? I've got a spare I'm thinking of moving on (for exactly what I paid), but It think I may have overpaid. Just want to gauge what these are going for. Thanks.

Thanks for the info. Ugh, I slightly overpaid...
My multi is due to arrive tomorrow. I pulled my Exvania Na-1 pcb out to get it ready and guess what. . took a shit- nothing but a blank screen. Most likely thanks to those fine caps Namco put on that board. Worked a couple months ago just fine 
I thought I recall reading someplace about some critical areas to look over on the pcb when these start leaking. A chip will cut power to everything else if affected, etc. or something along those lines. Anyone fill in the blanks for me on where I can start checking. For the most part, the pcb actually looks pretty good so this is a bummer. . .

try replacing that cap first and see if that work, basically if the cap goes bad the 3773 will never see the correct voltage and the PCB wont boot. sometimes the cap will take out this chip with it.
This is the 1st thing to try...
What's the status of the custom chips / leaky sound section area?
Got the video back by replacing the cap at C5. Now with video back, I am working on getting the audio back. Man those caps suck- every single one of them are leaking, and not the easiest to solder either. I have (3) caps left to replace and they will all be new. I am hoping once this is complete, the audio will be back. On the two volume dial knobs, one of them has some rusty color underneath. Can this be easily replaced, and is there a part # for this? Customs look good. Once all the caps are changed out, the only negative I see is the residue from the leaky caps left on all those mega tiny doo-dads scattered in between and around all the caps. I gave them all a good wipe down with IPA along with all the legs of the chips affected on the pcb.

I'm just waiting for my board to arrive (it's stuck in Japan since March). they recapped the board with Radial capacitor instead of SMD so withe the help of @AlxUnderBase I'll make a proper list with measurement for the recapping
there is a cap list here: http://blog.system11.org/?p=1120
IIRC I created a more detailed version for both NA1 and NA2 I thought I had posted them in the other thread but maybe not?

@rtw & @sk8er000 ... hope will help this capacitors replacement list ... but again , if someone else want to make improvements will be awesome

i've posted something about ... check this postCan anyone supply a real close-up pic of the section I have boxed in red? I have a trace from a chip that was suspect, but if I can get a good close up to see the tracks I can make sure I am good.
Thank-you, this is perfect.i've posted something about ... check this postCan anyone supply a real close-up pic of the section I have boxed in red? I have a trace from a chip that was suspect, but if I can get a good close up to see the tracks I can make sure I am good.
