Remove tuning knob

[Jeff Church]

I'm in the process of cleaning an Onyko TX-4600 Mk II exterior specifically the tuner glass cover. I can get the 4 retaining nuts off but for the life of me cannot figure out how to remove the bloody tuner knob. It has a set screw hole in it but everything I've tried, I.e., Allen head/Phillips/flat blade of various sizes, doesn't work. Any suggestions?

If it is still the original set screw, then what you need IIRC it is a 1.5mm but a trip to the hardware store and get a couple different sizes to try might be the thing to do.

Like Oerets, 1.5mm is what the tuning knob on my MCS receiver is.
It's possible yours is not 1.5mm, or has enlarged from use.
Menards has nice enough CHEAP sets of 7 Allen wrenches, often on sale for buy one get one free. 7 piece set currently $2.89. Not the most robust but good enough for occasional use.

It might actually be a screw too, I use jewelers screwdriver sets for those.
