Title: green bean, ego, pork barrel type of cap....
Post by: Donniedarkoz on November 22, 2012, 12:56:12 AM
hello I bought the pcb for these projects, I wanted to know what type of capacitor can be used for the smoothie in c1-c7, c9 are OK polyester? polypropylene? which do you recommend?
same thing (excluding the various electrolytic and tantallum) for the ego small bean and bork barrel
I live in Italy and usually ordered by banzai (wima, STMicroelectronics, panasonic)
for many capacitors I found tolerances 10% are fine?
in smoothie
smoothie in the transistors must be the same regardless of the hfe value? right?
thx :)

As far as the transistors go, Banzai sells matched sets of 2N5952, use those for the smoothie, just remember their pinout is different.

The WIMA box caps are fine from Banzai for the Ego/Green Bean/Pork Barrel.  I'd stay away from the "Greenie" poly caps just because they're usually a little too big for the pcbs when you get past 100 nF.

You might also want to check out musikding.de, typically they're parts prices and shipping prices are a little bit better than Banzai.

Have fun,

Curtis

You can also get a matched pair of 2N5952s from me, and I will ship to Italy. I match very closely.
