Just picked up
This win fall jamma pedestal cab I have tried to move Convergence ring but they are proving hard to budge ..



Chassis looks to need a cap kit for sure ..is this a convergence rings issue ?

 

[DanP]

Might be that the yoke has shifted forward or back?

That neo geo logo looks cool. Most likley the yoke ist shifted and DanP said. You need an squers pattern for best adjustments. Juat start the neo geo without cartige or set dip1 to on.

Will give it a go tomo

The rings are super stiff
Any tips on loosening ?

Your deflection yoke's got an open winding unfortunately. I'd bet if you pull it off the CRT it'll have corroded in one spot probably round where one of the yoke wedges are. Seen it happen a number of times with CRT's used with WG chassis of that era. I bet the CRT's either a WG's own brand (they use labels very much similar to Orion CRTs) or a Philips (or slight chance it may be a Zenith).
