Building the Audio Note Kit 1 SET amp...

If the 86db efficiency number that you posted about earlier is accurate (that would explain some of my failed attempts at De Capo/SET pairings) a healthy version of your amp may still, unfortunately, turn out to be a mismatch.

You know, that'll be an interesting thing to see and I'll let everybody know what I find.
Brian thinks we may be zeroing in on the problem, by the way. It's just that I've been to jammed up at work the past few days to do much testing! :-(

I'm hard pressed to see how it could be called a good match if truly not that efficient in the bass but may only need match to a certain extent depending on listening volume requirements and room size mainly. Its not working properly currently would seem to be the consensus so there is still a chance.

We think we are zeroing in on the problem! More to come!

The de Capo's are 92 dB, with a 6 ohm minimum impedance - - pretty friendly to tubes. My 35 watt EL34 pp integrated amp can barely crank up on the dial (I wish the speakers had a little less sensitivity!).
