It's just that for a long time I have been searching for a simple-to-use cct. drawing PC program that:
(a) doesn't cost the earth (read: free, ideally);
(b) doesn't require hours of study and a good knowledge of software 'things' to be able to use it;
© doesn't contain lots of other features that I don't need: such as pcb layouts, etc.
(d) produces clean, crisp schematics with a library of electronic 'things' which includes vintage components, like valves, etc.
I'm sure there is something out there somewhere that meets that spec.: it's just that I haven't found it yet. But I do recall seeing something that meets that description of mine many years ago in my then line of employment. And that ran under DOS on a PC/XT, too.

Have you tried one of the various Spice packages? LTSpice is completely free, and the schematic drawing is reasonably intuitive as these things go. You can just ignore the simulation aspects if that doesn't appeal. I've also got an old copy of B2Spice (http://www.beigebag.com/) that does reasonable schematics too.
I've had the same problem - hence all the schematics on my website were drawn as bitmaps in Paint Shop Pro (an example attached). It's tedious, as everything is a cut and paste exercise, but it does mean you retain complete control. But all those were done 10 years ago, and I doubt I'd have the patience or time these days.
Actually, it's not too bad once you get going... But I need to have another bout of research, as there must be something out there.

EDIT: The diagram should be totally "crisp". If it looks a bit soft, your browser and/or the image viewing software on the forum is scaling it. Right-click, choose "Open link in new window" or similar, which should give you just an image, and try clicking on it to expand it. Of course, those with widescreen monitors will probably be OK. Perhaps I should find a smaller one that will look OK on a small screen...
EDIT #2: The headphone amp should look OK.
