[Elecraft] Concentric knobs??

[hb9ari]

Hi Buck,

Thank you for this information !

As these knobs are hard to find in EU (may be impossible...?), i will 
send a note to Elecraft.
I will wait to add an order to this request...

73 QRO,
Rudi, HB9ARI

PS I had this same "problem" on an oscilloscope many years ago..
Seems to be the "thin"plastic wall for locking screw ?
