| Can anyone ID this vintage potentiometer |
| (1/1) |

I was repairing an old CGA monitor (Thomson 4020) and managed to break off one of the control potentiometers when trying to fit the pcb back into the case ;-( It's marked "7f 503". Schematics confirm 50k which is consistent with the 503. Anyone know the manufacturer? There are 6 adjusters and I'd prefer to keep them all the same; I popped the knurled shaft off the broken potentiometer so if I can find a 50k in the same series, even if the shaft is a different length, I can get it working. |

Does https://www.mouser.com/ProductDetail/Amphenol-Piher/PT15NV02-503A2020-S?qs=sGAEpiMZZMvygUB3GLcD7usKL8k3H%252BdSD61QApuMA%252BWxy1COaSwzcw%3D%3D fit your dimensions? Shaft seems a little wider, but you might be able to shim that. |

Thanks. Looks like it might need some modification but worth a shot. Still curious if anyone knows the manufacturer of the original piece. |
