Output Caps For Dehavilland Ultraverve

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? 

I'm currently switching back and forth between two amps depending on my state of audiophile neurosis at the particular moment.  One is a pair of DeHavilland 50A tube mono blocks with an input impedance of 100K, the other a Clayton 100S solid state amp with an input impedance of 47K.  Occasionally, when I'm feeling nostalgic,  I'll pull out my old BEL1001 solid state amp which I used for about 25 years and listen to that for a short while.  That has an input impedance of 27K.  I'm guessing that you were going to recommend a lower value cap, which would be less expensive and smaller, if I was only driving a high input impedance amp, but I would like the option of being able to drive a solid state amp as well, so the 2.2uf is probably the best bet.  Also, at some point I may move the amp(s) closer to the speakers and use a longer interconnect.  I'm not sure if the larger cap value would be advantageous for that or not...
