[R-390] The saga cont pt 7

[Tom Norris]

Why the insistence on Orange Drop type caps when the original layout was built to use axial caps?  I've yet to find any problems using axial packaged film capacitors instead, in fact most I've found have cost less and had similar specs re: temp range, ESR etc. (ESR shouldn't matter diddly squat in an R390, etc)  Other than those who were used to using Orange Drop caps from when they worked in TV-Radio shops and were simply "more familiar with them and think they are better" or such, why not put in the type of package that was there to begin with rather than wrestling OD's into place?  Besides, Sprague doesn't make them any more...
