The Burning Amp Festival- October 18th 2009 Sign ups - Page 3

I'd love to talk transformers with Jack - this is shaping up to be quite a do. I wish I had my GM70 amps completed to go up against the 211s, but alas, they still only exist between my ears. It's about time we had some big-a** triode amps at BA.

She won't miss you one bit

There will be a limited amount of LSK170 JFETs available in addition to preliminary datasheets on its P-Channel complement, the LSJ74, which will be released later this year.

I hope JC will be there, he has a strong opinion on those AFAIR.

I don't post here very much but I'll be there along with AMB. we'll be bringing our LCDuino-1 "i/o control processor" with us to demo. AMB will bring his usual collection of beta22, beta24 and gamma2 devices and I'll bring some IR/LCD remote control things we've been working on (pc board samples, too).

Pre-payment sent. Looking forward to seeing everyone.

paul, I am especially interested in the (long awaited) LSJ74 JFET. I presume that a LSJ109 might follow soon?

I'm slaving away this afternoon on my "Kingfisher" 7591A P-P amp using old Fisher 500B iron. With some sweat, it should be ready for the do. I'm bringing two tube amps and one composite gainclone (OPA627 + OPA541). Not that I'm so fond of the clone, it's just that I'd like do do some informal testing to see how it fares. It's definitely quite different in character compared to the tube amps. I'd class it as one of my failures, as I wasn't satisfied with its bench performance (specifically, square wave response). However, I don't ever listen to 10kHz square waves with 200 ns rise/fall times, so there may be some hope for the thing, even as a least common denominator sort of comparison. I think it would be instructive to plug in one of my tube amps to a decent set of speakers, then quickly substitute the clone - I noticed the difference right away on my system.
