For some obscure reason I have only ever skinned output caps.... I must try skinning all my caps from now on and see if there is benefit to be gained across the board. Alex, you can rest assured that there are sonic benefits to be gained from skinning output caps.... like Leo I wouldn't have mentioned it if it wasn't so.....

If skinning caps helps?
Try putting a ring around them, and see if that makes a difference.
Similar idea to curbing microphonic effects on valves.
just a thought

A bloody good reason to try and get rid of output capacitors !
I wonder if it would be worthwhile doing the same for feedback capacitors in solid state amplifiers ? Perhaps it is only evident with electrolytic capacitors that have relatively high signal levels through them ? It may be possible to leave the skin on , and dampen the capacitor with felt etc ?

Just a laymans thoughts. Felt pad for cap to sit on prevents harmonics from traveling into leads and throught circuit board. At what point this is advantagous is beyond me, but resinent frequencies do make sense, dont they?

Well I've seen people removing the outer case of those Russian teflon caps, I've never tried that and can't say I will  I'll try and find a link to a webpage you guys may find amusing  |

I must try this with the next X-CAN v3 I work on.... all these little macro tweaks certainly do add up and the beauty of them is they are as good as free (if you have hot glue and felt pads kicking about) so may as well try them out! Its worth a go, I only skinned a few on the decoupling lines but only heard a very small difference, maybe trying all of the caps in these positions may give a more noticeable result, judging by the effect it had on the Vcom pins its definitely doing something |

There's an idea...... howzabout skinning your caps and then varnishing them with Damar? |

Yes, that would be worth a try, I've seen some people recommend that c37 lacquer, that stuff is expensive though so varnish is worth a go, may give interesting results |

Yes, that would be worth a try, I've seen some people recommend that c37 lacquer, that stuff is expensive though so varnish is worth a go, may give interesting results I have half a litre of Damar so may well varnish a few caps and see what happens.... it takes ages to dry that stuff though, may also be necessary to key the surface of the caps with some 800 grade wet or dry before varnishing. Another thing and bang goes the safety vent but what about total encapsulation of an electrolytic (a skinned electrolytic) in resin? Yeh I know this stuff heats up like fck' as it cures and may well contract quite a bit but still worth trying. |

More on c37 here: www.ennemoser.com/eundf.html I think this c37 is probably just good old fashioned Damar bottled up in some "audio grade" packaging.... damar has the same properties and also takes an age to dry.... very much the same as raw linseed oil it takes weeks to fully cure and never becomes brittle. I have had great results applying damar to squawkers in the past but haven't even contemplated treating capacitors with it....... until now ;D |

Yeh I know this stuff heats up like fck' as it cures and may well contract quite a bit but still worth trying. The good thing with all these tweaks is that caps like panny FM's, Rubycon ZL's etc are cheap so its easy to get a bunch of these things and compare a few different methods, I fitted a couple of gold plated sockets to allow quick and easy changing of the different caps for testing. I'll have a look to see if I've anything suitable to try as varnishing too, I don't mind giving it a go, may actually prove to have good results  |

Thanks for the offer Mike, I'm popping into town later today, if I can't find any damar then sure, that would be great, I'm wondering if it can be found in something like art shops?

Yes, I used it to treat my squawkers (midrange units) with great results. |
