Building the Audio Note Kit 1 SET amp...

I agree with Charles. The stock tubes seemed to stabilize within a much shorter period of time. I'm not sure that it was even 100 hours, whereas these are still changing.
I don't know what Audio Note charges for the copper foil caps, but I'm sure that it isn't cheap, and likely for the same price or less he could get the Jupiters Charles, and they fit perfectly.
By the way Reb, I am glad to see you managed to get the upgraded copper plate. Small touch, but it's nice.

Hi John,
Yes, I also believe the Jupiter copper foils are an excellent capacitor alternative to consider. Rebbi mentioned the AN caps as these are the ones offered as an AN Kit upgrade if he wants to stay within the AN family. No doubt the Jupiter copper foil coupling caps are less expensive than the premium level 300b tubes. The possibilities with an amplifier such as this is considerable. When you factor in the potential future upgrades(if ever deemed necessary)transformers,caps,tubes, power cords etc. This amp can yield true world class sound for very reasonable cost. With this amplifier Rebbi has established a very strong foundation to build upon. If he stays put he still has a terrific SET amplifier. I can relate to his listening notes and appreciate what he's hearing with this amp in his system.

When I was having mine built by Digital Pete, I bought the Jupiter caps from Parts Connection and sent them to Pete. There was no credit for the stock caps of course, as they are part of the kit. Brian suggested V caps as an upgrade, but from things I read, they didn't sound like my kind of thing.

Which Jupiters did you get exactly, John?

Hi Reb,
I am attaching the link to the specific page. Scroll down to the ones that have a value of 0.22 uf.

They are $60.00 a piece, and as you know you'd need four, but the price is very reasonable compared to the Duelund and other competitors. Look at the comments about them on this site. And as I said, they are a great fit.
