Chime unit looks like a Williams to me.

Sinbad would have originally shipped from the factory with an electro-mechanical chime unit, B-12023, as you show from the GTB catalog. As Billc479 says, the other chime unit you show is for a Williams EM game.

Slightly later System 1 games had a very rudimentary sound board that used three 555 timer ICs to make three tones, simulating the B-12023 chime unit. This sound board was a direct replacement for the B-12023 chime unit, and was attached to the exact same wires that were designed to drive the physical chime unit.

Still later, a more sophisticated sound board was used (the picture of which you show in your original post) that could make a variety of interesting electronic sounds. Ironically, the processor on this sound board was more powerful than the rudimentary CPU that drove the game logic. The first game I remember us having with this sound board was Genie, but there may have been an earlier System 1 game that used the board. However, I believe Sinbad was too early of a game to ever have had this board installed by the factory.

The board in your game is probably an after-market sound unit that could be installed in early solid-state games to help "modernize" them. A few different third-party companies made these boards for operators, most notably the Wico Corporation. We had a few of the Wico boards on our location games, but I don't recognize the board in your game, so I don't know where it came from.

In any event, if you want your Sinbad to have 100% factory original sound, you will need a B-12023 chime unit for it.

If you can't find an original chime unit, you can get a new aftermarket one from here:

you are gonna pay 150 us plus for one used , so that euro one isn't bad and its brand new

I will look tomorrow, I believe I have a few extra units. In case you don't know, Steve Young at "The Pinball Resource" sells a rebuilding kit for these units.
Also for future reference, The first 3 System One's came with the chime box: Cleopatra, Sinbad and Joker Poker. All of the rest of the System One's didn't but they are all downward compatible to have the chime box installed. Chime box VS Sound card: Chime box for the win every time.

Read the above post from the one you just posted. I can probably help you out.

First chime box for Gottlieb was: 1970 "Aquarius"
I'm 99% sure on this.

Different coils though and they will have diodes on them.

They are not interchangeable even with the diodes removed. The A5195 have a resistance of about 11 ohms. The A17876 resistance is about 23 ohms. Has to be higher because the System 1 game is DC so you need a higher resistance coil. If you put an A5195 with a diode in a S1 game it will at a minimum probably break the plastic off the plunger. Putting the A17876 in an EM without the diodes will result in a weak chime.

It looks like the chime unit you were sent is from a Sonic (Segasa) brand machine. It's a metric clone of a Williams unit.

Wow, that's hard to believe because Williams chimes are the suck. They used a different sound box and a different mount system for the bars (which is what you have there) and they ended up being the worst, clanky things you ever heard. People say, well, they sound great rebuilt. I've rebuilt a bunch of them and they don't even compare to a Bally or a Gottlieb set. No matter what, they clank. Bally's are pretty good but Gottlieb is at the head of the class without question, but in quality and tonality of the unit. I can't see what kind of sound box they used there but if it's the same as Williams you got lucky that they sound good.

Williams was so bad I paid to buy a Gottlieb chime unit and installed it in my Grand Prix because the game sounded so awful.

You can really put anything in there, as long as the coils are the right resistance. Bally mounts to the cab a big differently but really as long as they are secured well to the cab, you can use any of them.

i have this but not solenoids or chime plates

Pretty amazing. Never had a Williams sound anywhere near that good.

I have a Close Encounters EM that came with the same electronic sound card. I replaced it with a Gottlieb chime unit.
