Output Caps For Dehavilland Ultraverve

No issues at all going into my friends mklll. Very easy to do. When I say no problem, I mean fitting the Jupiter and Duelund bypass. The Duelund silver foils are very small and the Jupiter’s fit.

The Duelund CAST is a great cap, but a 2.2uf value will be huge and cost you a Fortune! $900 for the two 2.2uf caps! My suggestion gives you as good sound quality for a lot less. The Duelund RS cap will sound great, but not as good as the Jupiter and Duelund silver foil combo. 

Another good choice if you don’t want to parallel caps is to go with the Jupiter copper foil caps, 600vdv. Get the 2.2uf value. Sonic Craft sells them for $140 each or so. They are spectacular. Right up there with a Duelund CAST in this position. Make sure you order them matched within 1% of each other. Dimensions are......

1.562″ X 2.125″

Check to see see if they will fit.

Thanks, Bill.  $900 for two caps, in addition to being rather pricey, does seem like a bit of overkill for a $3K preamp. Or maybe not.  I have no objection to paralleling the caps and will probably wind up using your original suggestion.  Would I be looking at an excessive break in period?

Some 100 hours gets you most of the way. 

What amp is being paired with this preamp and do know the input impedance of the amp?
