Pumpkin preamp - ordered by Steen , official making thread

Cap Sizing

Another newbie question 😱

Most of the capacitors in the shunty and pumpkin have a range of values that can be used.

In this case - is bigger always better

:devilr:

Like other notable things :clown:


I am currently using the values in the middle for most of the caps - should I go bigger??

:whazzat:

Beauties (Uglies) Contest

Need to ask the Beauties (Uglies) Judges in this thread.

So which of the below Uglies / Beauties will go well with the Pumpkin Carriage?

For the vaunted position of C4, C5.

And the contestants are:

1) Epcos Metallised Polyester - 10uF 100V (Blue like the boards!)

2) Arcotronics Metalliised Polypropylene - 5uF 400V 5% (Yellow!)

3) ASC Metallised Polypropylene 3.3uF 400V 10% (White and radial)

4) Jantzen Cross-cap Metallised Polypropylene 3.3uF 400V (Classy Black)

Cast your votes!

Me cheapie! Me have no money to buy the Mundorf - Silver/Gold/Platinium/Titanium/Uranium caps or the V-Cap teflons!!

Gotta be Black 'n Blue color scheme, So choose black or blue..

Everybody's using the RED Wima film caps though - so keeping to Black'n Blue is not really necessary.

I've got a all tube (OTL) headphone amp / preamp
(Bijou: http://www.cavalliaudio.com/bijou/bijou.php)

that I've just build a few days ago. Mine's a Barnes & Noble Special Edition (see pic).

I'll probably use that to test out the yellow and black beauty to see which I prefer as the output cap before soldering it into the pumpkin.
