I'm going to guess that the ROG Ally is generating that noise in the video signal when the amplifier is connected to it. Try that same setup on a different monitor and see what happens. Or try disconnecting the amp from the Ally, keep the Ally and amp powered on, then play audio through the amp...

If "resist a power-cycle" means that scores aren't saved, yes that's normal.

Are you saying you had the same problem I had, and removing the spacers fixed it? It's been a while since I looked at that and can't remember exactly which way I needed to press on those tabs to force the bezel to lock in place. I remember the bezel sticking way out away from the monitor at...

Attach it to a nearby screw. It's ground for the monitor, not earth ground. The monitor and monitor frame aren't connected to the cabinet's earth ground.

Ah, I see. Having that mold looks like it makes things easier. Still a tricky job that I wouldn't want to try again. After all that work of making a mold and rebuilding the cones, you definitely need to keep the stock speakers.

Can’t tell from a YouTube video how good it sounds. Probably fine for arcade games. Especially older ones that don’t sound great with any speaker. I’m assuming “restore” means you repaired the disintegrated cone on the woofer. The hard part with that, I learned, is attaching the cone to the...

By "up and running" do you mean you changed the sound IC? And it's still noisy? No music during the intro. I think music was added in the Dreamcast port, however.

Edited my last post to delete the lower impedance comment. That's not quite right. Different speakers need different amounts of power to drive them. The sensitivity rating is more important than the impedance. You should stick with the original speakers unless they sound really bad or have...

My OEM speakers were completely ruined so I never had a chance to hear how they sound. My guess is that they sound fine. That's assuming the refurbishment you did brought them back to their original condition. If it sounds bad, try different speakers. But not the speakers I'm using. Find...

Do a search for cleaning JAMMA contacts. You'll find different methods and opinions and you'll have to pick one. But if you are getting 5V with the 5V potentiometer turned all the way down with the CPS2 connected then the contacts are probably all fine. P.S. that 3.3V is for JVS and you can...

Correct, I do not recommend it.

Do you mean maxed out the 5v and reduced 3.3v? Those readings might be low if the 5v is at max. Between the PSU connector, the JAMMA connector, your meter, and the game board JAMMA connection there are plenty of places to lose voltage due to dirty or oxidized contacts. It's a good idea to...

Those components were chosen specifically for the amplifier, woofer, and tweeter combination that I am using and if any of those three components change, you need to change the components too. So the answer is no, you don't need them. But if you connect the same amplifier that I'm using...

By life expectancy I mean how long they will last installed in a CPS2 game. The battery manufacturer can only provide an estimate of how many years the battery will hold a charge before being installed in something.

No sub for the Blast. The ported speaker enclosures provide enough low end. My Blast City sounds better than my Astro City, even without a subwoofer.
