Tube Replacement: Single, Pair, or Quad?
sounds like a bias problem to me. my brothers marshall head did the same thing when tubes were changed with disregrd to biasing 
auxillary ground question
i had a set up like the one you propose. improved the sound of my system. then a guy on audio asylum informed me the way a lighting strike was likely to chose the aux ground as the shortest,easiest path right through the ole system. I immediately ... 
Amplifier hum: Does it need repair?
i've got one for ya if anyone wants to diagnose it. I have a VTL monoblock with an intermittent hum. sometimes it is preceeded by a volume spike (in a monoblock that is supposedly run wide open whith volume controlled at the pre...and it follows t... 
Burn-in time for 6550c tubes ?
My experience with tubes both in my monoblocks and in guitar amps is that they always sound constrained when you first turn them on and they open up after they warm up (the character change of the el-84s in my guitar amp after the first set of war... 
Have you ever moved to improve your system
didn't move to improve it but listening room was a huge factor in choosing a new home when i moved for other reasons 
What Guitarists Remind You Of SRV Or Hendrix?
not to digress too much but seeing Kronos Quartet do purple haze live laid out the meaning of psychodelic. Jimmy would have been proud. 
Best Value System
Boni, if you want to be truely amazed at what discrecionary funds can buy look here: http://www.higherfi.com/. It's where Doug's friends sneek off to over lunch.As to the best value system. In my room, mine pretty much wins. I've heard much better... 
Blues "must have, top 100" list?
Good list going so far except that Eric Johnson,while being one of the best pickers living who can do some mean blues, isn't a blues player based on what you get on his discs. Robert Johnson on the other hand...Everyone owes it to themselves to ch... 
Minimum tube power for Dunlavy SC-IV's??
If you look at VTL's web site they recommend a pair of MB 185s as a minimum for 10 in woofers. I use 185s with a pair of athenas and they work great. probably could get away with less. I think an ARC VT100 would work great as well. 
Vandersteen 1C with 845 S.E.T.
I have to weigh in on the more power as well. I had about 25 wts going through mine and like Ellery's they ran out of gass when you cranked them up, ultimately to the point when the tunes got a tad to demanding and the ole amp clipped. A couple of... 
Front- vs. Down-Firing Subs and Amp Issue
Hmmm. while not a sub my Dunlavy Athenas have a downward firing 10 that is rated flat to at least 30 hz and lower with room effects considered. the bass is extreemly tight and musical. I spent a lot of time dialing the speaker position in to get e... 
Tube power vs Solid state power, how much is enoug
blindjim, your last post hit on an important point controlling output and that would be amp design details. Especially class a/b verses pure class a. For the audio rig i have VTL mb185s which are rated at 230 w/side running on 6550 tubes. My guita... 
Why don't kids nowadays know about Jazz and classi
right on theduke! That's been my stand for quite a while now. interested, involved, questioning people are a danger to the government. Unfortunately those same qualities are kind of benificial to getting involved with complex music that requires c... 
Best speakers circa 77-79'
klipsch cornwalls were pretty darn cool too. Traded my Heresys for a pair...wish i still had em. 
Progressive Rock
In the 70's i listented to a lot of prog (still do to a lesser extent now) and the best system i assembled for that was vinyl based with a pair of old Klipsch Cornwalls. The dynamic responce of the horns was great for rock music. I have to admit i...
