[Hallicrafters] Capacitor temp. coef. in a SX-100

[Mark J. Giubardo]

Hi Skip,

Here is a link to Surplus Sales of Nebraska, they have a bunch on N750
capacitors in assorted values.

I found them and more places by doing a search on Google inputting "N750
capacitors"

Hope this helps, good luck with the SX-100,

Hi,
    I'm working on a SX-100 (with Gerry Steffers elmering) and believe 
the problem with bands 2 and 3 not operating lies in the osc. section.  
Two ceramic capacitors in that section are C71 a 1.0 pf N750 500v and 
C69 a 1.0 pf N2200 500v.  The only capacitors I can find (in Mouser) 
are NPO (or COG in EIA designation) with a 1 pf value.  NPO is quite 
different from N750 or N2200 in temperature characteristics.  What have 
others used in such cases?  Thanks.
