madbean Glam capacitor question

[snk]

Hello,
I am building a Madbean Glam using this layout. I like the way it sounds in the video, it's an easy build, and i have a couple PT2399 to put to good use

I am however wondering two little things (trying to understand the design choices) :
- The Madbean BoM (in the PDF linked above) specifies that one 10µF capacitor should be a tantalum one. On the layout, it is an electrolytic.
- On the layout, some 100nF (and some 220nF) caps surrounding the PT2399 are box type (yellow rectangle), some are red circles (so, i guess, ceramic ?).

My questions are the following :
- What would be the difference to use a tantalum (instead of an electro), and ceramics (over box or mylar) ?
- Would it affect the sound, or the circuit behaviour/performance (I know the PT2399 can be quite temperamental sometimes) ? Or is it just a matter of saving some space on the veroboard, and using what we have at hand ?

Tantalum is spec'd for the PT2399 +5v decoupling cap, IIRC. It's not absolutely necessary and I use electrolytic there all the time. Use what you have.

Not sure what you mean by yellow box and red circles unless you might be referring to a pic of my specific build. In that case, it's because I mostly have AVX box caps for 1n-8n2 and Panasonic ECQ-V for 10n and above. All film caps and just what I happen to use.

Thank you, Bean, that's perfect
(and thank you also for your great designs and website !)

... Glam built, easy to build, and it sounds fine 

Is there any way to add a pseudo stereo out ?
