Here's a trick that a fellow from Texas Instruments told me. It MIGHT help???? Be very careful!!!!<BR>
<BR>
This is about chips, the process of printing the numbers on chips alters the chemistry of the plastic around the numbers. So if the numbers have come off, you can sometimes get them back by applying the flame of a butane lighter briefly to the chip top. It may be that a heat gun will also work and be safer.<BR>
<BR>
The basic idea is that the ink changes the chemistry of what it is printed on and leaves a residual image, even after the ink is gone.<BR>

<BR>
<FONT SIZE="2">I just got a signal generator and I was <BR>
taking the knobs off to clean under them. <BR>
Everything was fine till I had the thought: <BR>
"I gotta be careful, this knob might break if I drop <BR>
it on the hard floor. That would be a bummer."</FONT> <BR>
<BR>
<FONT SIZE="2">So... <BR>
It's the clear plastic dial-skirt-bezel-thing that's <BR>
cracked. No missing pieces, just a crack, just a big <BR>
nasty ugly crack. Here's one just like it on ebay. <BR>
You can see what the knobs look like.</FONT> <BR>
<BR>
<FONT SIZE="2">http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem=1361497056 <http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=1361497056> <BR>
Or search for item 1361497056</FONT> <BR>
<BR>
<FONT SIZE="2">I'd like to fill the crack with something so light <BR>
doesn't reflect off it and it won't be so visible. <BR>
Doesn't have to be strong. <BR>
I can use a vacuum chamber if that helps.</FONT> <BR>
<BR>
<FONT SIZE="2">The good news is that it works. Freq range is <BR>
1mHz-1.999999999MHz, so I thought it would make a <BR>
good LFO, tuning standard, and ring mod carrier.</FONT> <BR>
<BR>
