[R-390] That's more like it!!!

Tue, 27 Jan 2004 19:05:02 -0500

What I said was: "I don't get into hair splitting as to what brand and what
color cap I should
put in as a replacement...".
All these discussions about whether to "orange drop" it or whatever, seem to
be completely ridiculous. Any ham who's attempting to do repairs on
equipment, should be at least familiar with basic components and their
application, i.e. the types of capacitors and resistors available, and the
application by type and voltage ratings. This is basic!
It looks like sometimes someone uses a certain brand or type and then others
follow it blindly and that brand/color becomes "fashionable", without the
correct design procedure and part selection  behind it.

BTW I'm an Electrical Engineer by education and in my professional career I
specialized in the design of  high-power, wide-band amplifiers (typically
between 10 KHz and 220 MHz, up to 10 KW), and HF tube and solid-state linear
amplifiers for communication systems...

Seriously, one doesn't have to be an engineer to select parts wisely....

Hi Guys,

        I don't know that there is any one "Accepted" cap specified by this
group of believers but I think the Orange Drops are probably the most
used...but certainly not the only cure for what ails these radios.  I have
heard of many caps of similar design being used.  I for one would prefer one
with the leads coming out the ends like the originals....they would be
easier to mount.

Cecil....
