[Test-Equipment] Scope knobs needed

[John King]

	*   
I have a Hewlet Packard 1710A Oscilloscope and the knobs have 
deteriorated  with time and some have become brittle. I need some 
replacements in good shape. The small knobs on some of the verniers and 
the small knobs on the Chanel A and B volts/Div . The small knobs are 
worse than the others.

Are there any knobs for the HP 1710A available out there? If you know of a 
source, please let me know about it.  If you have any, please describe 
and give me a price.
The knobs do not have to be HP but they are gray and I would like to find 
direct replacement knobs and NEW would be best, but I am open to what is available. Let me hear from you . Suggestions appreciated. Thanks and 
73. John, K5PGW
