hi there:
I just cross-checked with a diff. PC (win98/IE), that didn`t have the pdf in it`s cache:
it worx,
BUT: not by right-clicking/save as,

but only left click/view, because it is a pdf-viewer frame within a site...

try again clicking directly: from there on, you can save it (every page needs to be saved individually, though!)

and by the way: it`s not that usable for our purposes... (small control range) :wink:

usually only on sat- & sundays...

(I do get a lot of "404" on this forum today, however...
maybe that`s because of the latest virus-attack on the web:
millions of emails bouncing around conc. the soccer
worldchampionship-tickets...)

And not an opamp or JFET in sight! Those were the days when people really had to know what they were doing...
Dig the inductors on the output filter - reminds me of stuff I saw in US Navy radios decades ago - now that's old school! :wink:
