Re: New Astro City Lines On Screen
frequency header on the main chassis
low is 15k
high is 25k
it looks like wrong res or maybe horizontal hold needs a tweek- i think res though

Its on 15K. The 4pin connectors are labelled 15K and 24K and are next to each other.

Wires for vertical yoke are in bad condition.

Adjust the trimmer for horizontal hold. It's one of the many along the edge of the main chassis.

Re: New Astro City Lines On Screen
Yes, it is. The right dip switch controls resolution. IIRC up is 15khz, down 31khz.
EDIT: manual confirms this, https://wiki.arcadeotaku.com/images/9/9 ... manual.pdf (page 6)

Re: New Astro City Lines On Screen
Did you set the chassis back to 15kHz?
If so, and if you have the Atomiswave set to 15kHz then try adjusting the 15kHz horizontal hold pot on the chassis. It's the one marked H.H.15
There's a image of the pots [here] on the Wiki.

Re: New Astro City Lines On Screen
Make sure your chassis is set to "LOW".
Set Atomiswave to 15khz.
Adjust the pot circled in the pic below (H.H.15):

Re: New Astro City Lines On Screen
I'm sorry I'm a real noob, the chassis how can I set it to low and the pot you circles how do I adjust it like how is it supposed to look, I'm sorry I'm asking a lot of questions and thank you.
Re: New Astro City Lines On Screen
The arrow points to the "LOW" 15khz setting. The other connector is for "HIGH" 24khz.
You have to turn the pot while the monitor is on. When the image on the monitor stops looking like a squiggly mess, you've found the correct spot.
It looks like the pot still has factory glue on it, you will have to pick that off.
