Title: Capacitor Upgrades Post by: Neozelus on March 09, 2009, 06:53:51 AM Hi there,
Real new to all this but just wondering if anyone has tried using the Sozo mustard re-issue or the Jupiter capacitors, and whether it's worth spending the 100 odd bucks to upgrade them? Thanks! Title: Re: Capacitor Upgrades Post by: mcinku on March 09, 2009, 07:19:44 AM I wouldn't spend another 100bucks on caps. Sprague caps are not junk... even mr. Dumble him self was using them... no to mention companies like Fuchs, Glaswerks, Bludotone, TwoRock just to mention a few.
You better spend that $100 on some NOS tubes or some good speaker... that sounds much better idea to me. ???

It's more the values that affect the change in sound than the brand. I know some people swear by certain brands of caps but I really don't think you'll notice a difference.
Better to spend your money on the output tranny and choke...there's some threads on here about that. http://ceriatoneforum.com/index.php?topic=981.30 Title: Re: Capacitor Upgrades Post by: blfmmm on March 25, 2009, 02:16:02 AM Silver mica caps are considered by many amptechs to be probably the best general purpose caps around. I upgraded to them on the slope resistor, bright switch, treble cap, and negative feedback loop (also swithched the val. of feedback loop cap to 500 which is the stock Dumble val. according to the dumble schematic that I have access to. I liked this value better) The silver micas noticeably smoothed out the tone and best of all they are only like a dollar a piece. When people try to tell you things on this forum like "if its good enough for Dumble then it should be good enough for you" just remember that you decide for yourself what is good enough for you. Also, this amp isn't a Dumble. The magic of Dumbles was that they were built by him and tweaked by him specifically for each client. He is a one of a kind master builder and could probably make a transistor radio sound amazing. Good luck, have fun, and remember the sky is the limit. My OTS sounds incredible.
