why 2x100mf ? 1x50 isn't better solution ??

I am way down on the totem pole of electronics knowledge but I believe that two 100uf are used to sum the voltages.

Hi keithrick
yes is a trick and R is trick to balance ,but is bad eletric solution!
I see another trick ,a cap in parallel to diode for low commutation noise , hifi used diodo schottky or ixys fred
I'm not expert in amp guitars...only hifi.I don't know if there is a difference in sound!!
I start to order a component what solution advised to me ??

Re: First Stage Filtering
My advise is to do as close to what Dumble did as possible if you are building a clone of his amps. Hopefully somebody who knows more will chime in, but in essance I would suggest following a schematic or layout that has been posted and then tweak with some of your ideas to make the amp "yours" 
Good luck with your build.

Manu,
I'm not an expert on guitar or hi-fi amps, but I believe the difference is the amount (and type) of signal distortion that is required to make a guitar sound decent. Most guitars sound pretty bad when recorded direct or played through a PA. The amp is the other half of the instrument. While there are places in the amp where you might want to apply hi-fi principles, ultimately a guitar amp must distort the signal to sound good. (I'm not talking about clipping, although there is that too.)
As for the 2x100uF versus 1x50uF, it may just be the parts available 20 years ago. The first caps can get slammed with an awful lot of voltage at turn on. I'm still not sure if anyone makes a 600-700 volt 50uF cap.
