Cap Rolling

My treatise on the subject of using bypass caps is published below:

Don't.

Hah, cool. Although I do respect your answer, you've peaked my curiosity.

Thank you, Doc (and PB!) 

Honestly there was nothing more cool than when I listened to the C2A for the first time completely stock. Mods are fun too. I like both.

I am using those new Mundorf evo oils in my crack2a as well, they cost a lot. I think they sound cleaner than the stock ones but they are warm sounding over the already warm crack sound. I think they were designed for speaker crossovers, maybe sound less warm with transistor amps.

Hello Bob,

How are you liking the C2A? I put in the Evo Oils after the TwoQuiet Stepped Attenuator upgrade so I can't speak on how they sound without. IMHO, the TwoQuiet was such an awesome upgrade to experience!

The 0.1uF is in series with a 220 ohm resistor. The time constant (R times C) is chosen to keep the 431 chip stable, so the product should not change very much - maybe +30% to -20%? I favor keeping the resistance value near 200 ohms so the effective source impedance is similar at high frequencies to the regulator's low frequency source impedance.

So a 600vdc cap would through this off and have a negative effect?  Just getting clarification that it is the vdc you're referring to because there are some pretty fun seeming inexpensive .1uf caps, but quite a few are in the 600vdc range. 

Thank you!

The cap voltage isn't critical in that position, but it should be rated for at least 250V.
