I just acquired a Heathkit DX-100 for repair/restoration for personal use and 
am looking for a few resources. I need a red knob for the 6146 grid drive. 
There is also a piece of the VFO dial broken out. If I can't find a replacement 
it is not a big deal because the rest of the dial is in decent condition, but 
if I had a better one I would use it. The face plate of this radio is also only 
in fair condition. Has anyone come across a source for replacements like I've 
seen on eBay for SB-200's and HW-16's? Lastly, without going to the paint store 
for custom mixing has anyone picked up the two shades of grey paint for the 
cabinet? Again, if not it is not a big deal. I'm sure these grey colors should 
be fairly easy to match or come close to.

I'm looking for comments also on the antenna loading circuit. The original 
coarse/fine arrangement has been replaced with a 3 section variable that 
measures 1100 pf to 2920 pf using my ECG Capacitance meter. The DX-100 article 
in the June ER Magazine makes reference to Heath's modification using a 3 
section variable totaling about 1200 pf. The original circuit switched in 200, 
400, 600, or 800 pf and then used a 250 pf variable allowing matching of 50-600 
ohms. Since I will be using unbalanced (coax) does this value seem appropriate 
and what might I expect? 

This transmitter also has been modified for use with a SB-10. The modification 
is done nicely with the 0B2 tubes mounted underneath and a rotary switch on the 
front panel on the right side providing a geometric balance to the meter 
switch. The only negative to this mod is the way holes were hacked in the rear 
cabinet screen material for the SO-239's.

I thing it is well worth the $49 I paid on eBay. The seller lives near my 
brother who picked it up and met me at a family anniversary party this weekend 
saving shipping charges.

I can't help you with the restoration....  as far as custom mixing of
paint, most quality stores will use a "meter' to get the exact color
of the object to be painted....  no extra charge   <<?
photospectrometer maybe??>>     klc
