PC Engine GT stereo sound

[jonzo]

Hi everyone,

Recent recruit to the site, been collecting and modding console for long time and just got myself a PCE GT (and most other PCE systems!).

Was sold as fully working, and the screen is very good but when I plugged in headphones found I only had left channel.

Was back-n-forthing with the seller, they gave me some refund and I agreed to take care of it myself.

Anyway, I opened it up and it was a bit of a mess - partial cap replacement (including some strange additions).  That wouldn't have been a problem, but several soldering pads were gone (and still electrolyte residue everywhere).  Anyway, long story short I ended up fitting remote caps and kynar wiring them to the back of the board - the post here as very helpful:

This is pic after I cleaned up the mess of caps and electrolyte:





Anyway, my question relates to the stereo - it sounds "not quite" stereo.  For example with the Street Fighter 2 intro music, there are those drums at the end of the tune - they bounce left to right on my Core Graphx, but it doesn't sound stereo on the PCE GT with these changes (still 100 times better than Left only).

This is how I've soldered in my new caps:



So I guess my questions are:

1) Am i expecting too much from the stereo sound from PCE GT?
2) If it is wrong, can anyone point out the error in the points of soldered from?

Thanks,

Always good to have another tech here!  Keep us posted on this project.

I hadn't planned to get too technical with this one.  Was hoping it would be all good and I wouldn't be smelling that nasty smell again so soon.

That post I mentioned saved a load of time, I had already started with the multimeter and had soldered in 20 or so wires to trace the audio.

Once I get the audio sorted, may have a go at installing a 2.5" TFT screen I just ordered.

I've got a bunch of briefcase CDs that need my attention after this

Welcome, comrade .

ASIDE: I was hoping that your moniker "jonzo" was in reference to the fabulous "Jonzun Crew", but, sadly, I don't think this is the case.
