I had an old, but still sealed Antec 380W ATX power supply blow out its capacitors upon first use out of the box (and I mean this literally, there was smoke spewing out of the power supply). If this is anything to go by, I would expect the Game Gear's capacitors to be faulty too, not to the same extent, but likely either leaky or dry.

No I don't. All I know is that Game Gears without a BIOS use Genesis Model 1 power supplies instead of the typical Genesis Model 2 power supply.

Thanks for your message. If I weren't insanely busy right now (my posts on Sega-16 are a way of procrastinating to avoid the task I have to do ) I'd gladly make a recording. Remind me in a couple weeks?

Hi!

I just did the fix in the thread and it totally fixed the problem. Go figure.

But I've put a 20KΩ potentiometer instead of the fixed resistor in lieu of the 12K/20K/whateverΩ*they put to find the sweet spot and after a long session of testing I discovered that ~18KΩ is a good value which will give you 100% output when the slider is maxed out.
Anything less will start saturating the amp thus giving distortion.

Now I'm wondering if the 10KΩ resistor is a good value or if it's too low for the circuit... considering the original one was a whooping 47KΩ!
The point is that everything there is surface mounted and I'm afraid of soldering and desoldering stuff: if I lift the trace it's game over.
I'll just keep it at 10KΩ and call it a day: the sound is superb!

Have a good one!
