I bought a chinese 'desoldering iron' that was a copy of the Hakko one but never could get it to work right unfortunately! I should have bought the real Hakko!
Thank you for taking the time to film this! This was very interesting to watch. I didn't know much about impedance or how the sound worked on these style cabinets - thanks for the information! I'm glad you're feeling better by the way, you mentioned that you weren't feeling well a few videos back!
Great video guys,she came up trumps in the end with a little TLC....Another great sega simulation game saved !! Thank you for taking your time to film for us,looking forward to the next 1,still have loads of your vids to go through,been a bit distracted lately squirreling parts to restore our lovely classic range rover :) x
34:28 I really can't get over this song at all. If I end up being in NYC again the next spring or something, I'll make sure to listen to this damn song when I go out for a big adventure myself like Coney Island.
Ron, impedance (pronounced im-PEE-dance, because it impedes the flow of current) is the sum of DC resistance and AC reactance. Your meter is only measuring the DC resistance part, so you'll typically get around 7ish ohms because you're not measuring the AC reactance part. But the DC resistance is most of the impedance, so your test is perfectly fine. If the speaker coil is open (meter reads OL) or has a bunch of shorted windings from overheating (meter reads only a couple of ohms or dead short) , your DMM will tell you. By the way, sometimes a speaker reads open because one of the tiny coil wires connected to the terminals has come off, and all you have to do is resolder it. It's always worth checking. If the coil reads open because it melted, then it's time for a new speaker.
Ron: Thanks for filming these for us all! :) Glad someone else noticed that engmcgil. It made me grin to hear Ron talking about impotence, like Sega cabinates have sex lives and can't keep up xD. I guess the poor thing did have bad ROMS, thats enought to dampen anyone sprits ;). I'm sure he knew he was doing that, as later he commented "its shlonged". hahaha.
Use vinegar and aluminum foil to get rid of the pitting on the chrome "pipes". It works like magic. Just crumple up a wad of foil, dip it in some whiter vinegar and use it to scrub the rust away. Rinse it all off and Bob's your uncle.
The bottom of the cab is looking great at the end, you did a great job tidying it up. Getting rid of that silver t-moulding is a big improvement too. I spy a Time Crisis 2 topper piece at the end there too. 😉
Yes I feel a lot better. Almost back to normal, this 'flu' or whatever it was lasted almost two months. I was only sick about 10 days but after that I still couldn't breathe quite right. Pretty wild!
The hairy hand thing is another form of "Parkinson's law of triviality". Another example was in the game Battle Chess, the graphic artist knew management always had to change something to justify their jobs, so he gave the queen a pet duck, making sure it was easy to remove. It worked, he just removed the duck and they didn't ask for anything else.
Another example from the Wikipedia refers to how management would spend a good 50 minutes deciding what roof material to use for a $350 bike shed at a nuclear power plant but about 5 minutes approving a $10 billion spend on the station.
Funnily enough, on my PCB for this game, which has the Rev A software (SEGA 1997 copyright only), there are periodic audio glitches that happen when you turn off the demo sound. Sometimes the name entry music locks up after the game ends. It happened to me on a real machine though, so maybe it was just the way the game was programmed haha. Also fun fact: The Japanese version of this game had a different attract music, with vocals instead of the "wah-wah" talk box you would hear blaring across Dave & Buster's.
For the speakers next time find a set of old PC speakers. The Altec Lansings were really pretty nice considering and shielded as well since they were made to be placed near a computer monitor. If you troll the thrift stores you can often find them for pretty cheap. Strip the speaker out and mount it where you need it.
@@LyonsArcade ROFL, I am the same way. I have over 10 computers sitting in my place right now. 3 of them I just got fixed up so someone could use them if needed while all the virus junk was going on. I have my desktop that is running, my wife's laptop that I can't bear to use since she passed, another laptop that I use from time to time for different stuff, my server which is dual Xeon X5690 96GM ram beast and my router which uses dual Xeon L5630's. Not to mention the core i7 tablet someone gave to me and my android phones and tablets. I once mentioned I heated my house with pc Graphics cards this winter, LOL. If I was closer you would probably be calling to see if I had stuff sitting around when it comes to computers. I actually have some computer speakers just sitting here. I also ended up with a point of sale system that was used in a restaurant at one point. Just need to bump the RAM in those and install some SSD's figure the system is worth a hundred or so once it's up and running.
if the amplifier has bad components it could be putting out DC current on the speaker outputs and its not always the main output driver itself .. Components like bad caps or open resistors that manage to impact the amplifier bias would certainly do that.. That issue if bad enough will fry the voice coil in the speakers on the effected channels explaining why the speakers are open .. With no audio signal present there should not be any "dc" voltage present (more then half a volt is bad referenced to ground ) Speakers should only see variable audio signal AC on there terminals .. A amplifier power supply that is not supplying clean DC to amp can also do this.. looks like this game has its own separate power transformer for the audio section, as you know use care with games imported from japan (100 v) as people will update the switching power supply, but not address the separate power to the audio amps or monitor causing them to fail from over voltage stress . as far as DC on the speakers one will often hear a hum as a side effect to this. if its not fixed it will also fry any new speakers you install. an example of this issue ,, ruclips.net/video/-hChkNyf1V8/видео.html
Nicely put! DC voltage on speakers will kill them, depending on voltage and coil resistence (different than speaker impedance). The reasons for an amplifier putting DC voltage on the output are various, depending on amplifier topology. In push-pull circuits, if an output transistor goes short, it will ouput rail voltage directly to the speakers and fry them before a fuse can blow, it happened with me once. It is always a good idea to measure DC voltage on the deffective amplifier to help with diagnosis. Otherwise, there is a risk to damage newly installed speakers. After amp is repaired, it is necessary to measure DC level again to make sure it is under 50 mV or so. There may be pots on circuit to do that or simply the amp circuit is symmetrical and needs no adjustments.
Thanks for sharing....question for ya Ronnie. 2114L2 static ram is there a good replacement or somewhere you can still get them...its for a galaga board. any help would be fantastic Chris.
What I always have to do is just buy them on ebay, there's not really a good obsolete IC place that I'm aware of online, if you do buy them on ebay don't buy them from China, you can get them in the US usually or Europe. From time to time the ones you get even domestically will be fake ones the seller bought from China, but if you check their feedback first usually they will have previous complaints if they're sourcing their stuff from China.
Wow this was over a year in the making. Seem's like you're working on a feature film hehe. When you said that both speakers were bad, that normally means one thing: The power amplifier shorted out and blew the speakers. Not a good idea to replace the speakers without repairing the amplifier first hehe.
We made it through :) I don't know if it came through clear in the video but I replaced the entire audio amp board, I tried repairing the old one but no dice.
The resistance climbing or not being stable indicates there is likely a capacitor in the harness across the pot. Using a 4Ohm speaker instead of an 8 will affect the amplifier in negative way. It is good to order proper speakers.
@@LyonsArcade You did really well with this one. It was a mess when you started. 🙂. The amp board likely killed the original speakers. Sounds like some kind of biasing issue made the chips get hot, but hard to know. Finding a new used board was good. I always admire your work. You make it look easy and explain things in a way that anyone can understand
Ron ignore those stupid comments I wrote on the Robocop game, I had one too many drinks and wrote some bullshit on some video's. I apologize for writing them.
I want to do this as a hobby if anyone in MA or southern NH wants some free hands let me know.. always dreamed of working at an arcade. I'm doing good now but would like to work at an arcade as a second job

Impotence also impedes the flow as it were, just not of electricity 😂
Thanks for the info!

Yup it's pretty nice, we did another video of playing it, coming soon :)
A game about riding motorcycles and has Harley-Davidson logo on it.
But it doesn't have STEPPENWOLF BORN TO BE WILD!
