Hi All,
I have a nice HRO 500 except for the fact that one of the knobs i missing the aluminum insert. Seems this condition is pretty common on these types of knobs. Does anyone know if there are replacements available? I suppose I could remove one and take it to a machinist to have a replacement made if need be.

Thanks
Steve

I spoke with Charlie. Very nice guy. He indicated that the he thought these were standard Raytheon knobs so please check your parts boxes for me :).

Doesn't matter the knob style as long as the insert is approx .74 inches in diameter.

Thanks

Steve

Hi Steve,

I have several of these knobs that I picked up for NCX-3/5 restorations. I would be happy to send you what you need. I probably have enough to replace all of them if you needed...

Let me know,

Bob AB1MN

Greetings to Steve and the Forum:

I have three knobs, but none of them has a .74" insert. In the photo, from left to right, they measure .805", .629" and .570".

hi Jim,
Thank you very much for looking but I don't think they will work. These knobs defiantly have .74 inserts.

Update,
I ordered some knobs online that "might' do the trick. I'll only know for sure when they get here.

So pause on Digging for me , for a bit :).
