Did you also check and replace the transistor that drives that coil? That might be the reason the previous coil went the way it did.

Sure, all these are checked and repair where needed.

Awesome!

Nice work bringing the game back to life.

Note: the original knocker coil is a 26-1200 (26 gauge wire with 1200 wire revolutions). Your replacement is a 23-800 coil which has much lower impedance. There is a risk of that driver transistor failing again from over current because of the low impedance replacement coil.

Thanks for the info. I did not know that the original coil is a 26-1200 to be honest.
Do you reallly think that this might cause to the transistor?
The reason I am asking is because parts in Greece are hard to find and especially now with the Corona virus its even harder unfortunately.

To be honest, yes.
Do you have any low ohm, high watt resistors you can put in series with the knocker coil for now?

BTW, you can find the coil part numbers in the Star Gazer manual:

Thanks for the information mate. Really helpful.

It looks like a few of the transistors on the SDU are unused too. I'm pretty sure you can remove one of them and install it in place of the blown transistor if needed. For instance, the schematic shows Q11 and Q14 both lead to 'open', meaning they are not being used. There's a few others too, looking at the SDU schematic.

Actually this is a really good idea. Unfortunately I don't have the skills (yet I hope) to do it.
I think the most safe thing to do for now is to find the correct coil.

Since I know a guy who built a StarGazer from scratch, definitely yes. Worth it.

Totally aggre. I have seen people giving life to pins that were totally destroyed more than once. Plus that in this particular case this Star Gazer it's the only one in the entire country. So right from the start for me to repair it was the only logical decision regardless the time that will take to do so.

Thanks for the links mate. Really helpful.

Side bars were severely damaged. Hited, scratched, bended etc.

You could have probably sanded that then buffed out most of that damage with a buffing wheel and some heavy rouge.

Totally agree. I did sand them a lot but the damage was beyond that unfortunately. They had very deep scratches and markings. In the before pictures you can't really tell. Plus that I miss the proper heavy equipment.
I had to straight them out first by hammering.
The only way to hid this was to coat them some how.

This is looking great. I'm excited to see how it turns out in the end. Have you figured out anything more about the different play field art you seem to have?

Playfield it's an issue here to be honest. I still don't know what I am going to do with it. Replace it will cost me a fortune. It's not only the purchase of it but also this ridiculous high custom house tax we got here. At the end it will cost double the money for a new playfield. From the other hand it will be nice to keep the re-done playfield. It's a form of art, so why not. But still this will also need to be nicely repaired.

It certainly has its flaws however I am very proud for what it is now compared to what it was before.

It's looking good, especially compared to the trash heap you started with.

In a previous post I showed how I painted the side bars. Well this didn't worked out. I didn't like it. So I removed the paint and I sand them to death with many different sand paper sizes. Then I polished them and I think that the result is really nice.

It took me several hours but it was worth it.

My advice, never paint the side bars.
