Hi all,
I have a rather sad 5B44 with broken timebase knobs. My copy of the service manual is a not a clear enough scan to tell for sure which part numbers these are so I cannot give specific references.
The knob(s) are concentric and have skirts with the sec/div marked on them - or would have if it still had them.
Can anyone help with identifying the correct part numbers please?
Does anyone have a non functioning 5B44 with intact knobs they would sell for parts or part out themselves please?
Or does anyone know where to look for these parts?
I have been looking on fleaBay intermittently but not much luck esp. with not knowing the exact part numbers I need.
Thanks and kind regards,
Daniel

What is not clear? Although the index numbers on the parts exploded view in the 5B44 manual at TekWiki are a bit hard to read, I find them legible enough to find those index numbers on the mechanical parts list.

Hi,
maybe this link is helpful for identifying the knobs based on images.

Best regards

The part numbers appear to be 366-1532-00 and 366-1533-00.

I suggest that you contact the VintageTek museum. They might have parts or a donor.

Thank you all that responded, I have now contacted VintageTek Museum to inquire. QService where not listing these particular parts

Thanks and kind regards,
Daniel

Speedy reply from VintageTek Museum, unfortunately it's:
"We no longer have the volunteers who had the time to look for parts and ship worldwide. Sorry we can’t assist in these kinds of parts searches."
Oh bother! The hunt continues.
