Can you please explain the difference in these two types of caps?

sure see the pictures. Flat wound are designed to minimize real estate on a board. When winding a flat wound cap it is virtually impossible to maintain constant film and or foil tension, with a round wound it is easy to maintain constant wind tension. Constant tension is much preferred. Want an even better cap? Stacked film or stacked foil and film are about as good as it can get see picture. Hope this helps you.

What specific caps would you use when replacing the original caps, whilst preserving the original sonic characteristics and perhaps improving the sound?

Curious as to how you know this...

BUT IT'S NOT FACTORY APPROVED AS PAUL INTENDED.

 

(surely he never had to balance quality or design goals with parts cost for mass production)

 please don't shout.  a flat wind is not as good as a round wind and a round wound cap is not as good as a stacked construction. it is what it is. choose and use what ever you like.

 a buddy used to wind complex fine gage coils and also had some cap winding equipment, he spent a fair amount of time picking the brains of guys who designed and sold winding equipment to find out what he needed to know so he could build his own machine. he is a clever cookie with a sharp mind and has designed and built or modified much of his own equipment.

I´m in the process of re-caping my Heresies as well and have a question. I´m looking for those white, square bases that wuzzer used to fix his capacitors to the board. What do You call these parts?

 

If you Google 'zip tie mounts' you'll find lots of different styles of them.
