Aside from shielding users from the potentials that may appear on the capacitor cans, the ugly plastic has a couple other advantages:

If you need to replace it, look at it and there the values are in plain text
Some caps are wrapped in such a manner as to contain or direct a large leak / minor explosion so that they do not turn into little bombs

Ah yes. I reccommend DC-3 paint since C-37 is a copyrighted magic sound improvement coating and costs too much.

Wall Candy brand white paint will help damp mechanical resonances reducing microphonics, and tasty too. Users agree, it improves psychoacoustic quality, Nero's fiddle sounds grandiose on systems so modified.

My aluminum cans don't; Rubycon, Jamicon and Mallory have all worked for me without conductivity to the barrel. I have certainly not tried every cap out there and peeling the label can be very destructive depending on the result you require. Like I said cheap and dirty. It is a cheap trick and it has worked for me and it is not for everyone.

Please post this schematic or your favorite version of it, it sounds nice.

Nothing to it, it is clean and the circuit leaves very little to the tube to color the stage. Great for a line stage that you require only a little gain from, from time to time. I wasn't looking for "warm" when I decided on building this. I must have studied and downloaded a thousand schematics and I'm not exagerating. I want sterile and clinical on a linestage perhaps you don't.

Try it to see. I did it in a weekend including the case.

Shawn.
