    RSW-12 Subwoofer issues

    The sub is still plugged into the same power as everything else.

    I have some low end contractor grade Velodyne subs that absolutely hate having their AC power cables anywhere close to any other power cables and get angry just as you describe. Try plugging the sub in somewhere else and make sure the cable is isolated from other power cables. 

    Active Bi-Amping/Tri-Amping FAQ

    "The pace, rhythm and timing of an amplifier (PRAT) need to match.

    PP and SET do not match up well.

    Amps with no global feedback do not match up well with amps with global feedback. "

     

    I am glad this old thread was brought back up. I think most of have always believed SS was best at bass reproduction & tubes had the best mid range, or at least that was my experience. Since I started down the bi amp road I have never tried a different amp for my bass, thinking at the very least my Crown K2 was a good choice for the bottom end. . I have tried several different amps on the top end with very noticeable differences. If the quote above by djk is correct I have been missing out on another opportunity for improvement. My set amps on the top are zero feedback & the Crown has a dampening factor of 300.

    Would love to hear from other bi amper's of there experience that they have tried matching both amp's with no feedback or not matching.

    Need to get motivated & dig out some of my other zero feed back amps & try them on the bass. May bee the Bat vk60 or the Moondogs (uppps just sold the Dogies) :rolleyes: Dang sold the First watt F3 as well - live an learn.

     

    Well i managed to get about 20 hours on a new Decware Torii PP 25 watt dual mono on my Cornwall III's. This PP is voiced very closely to the Rachael that I have around 40 hours on. Both have the stock tubes. Lots of EL34s and 5U4s in here. Straight out of the pelican case, this thing was already throwing out a great image.

     

    I finished re-configuring everything this afternoon. Have the Rachael's variable output feeding an input one on the Torii for a full tube bi-amp of Cornwall base box with an Eminence N320T/Selinium bi-radial midrange, and a B&C DE120/Faital Pro elliptical HF. Feeding the Rachael with the dedicated stereo outputs of an Oppo 105. Connected digital coax to the Oppo is an M-Audio sound card. Straight FLAC 44.1 Redbook rips.

     

    For a system that isn't even close to being broken in, this is nuts!

     

    I'm really looking forward to getting some serious time on this setup.

    I knew that would get everyone's attention! 

     

    Nelson Pass is brilliant.  I can't imagine anyone in the audio field thinking otherwise.  Given his respect in the audio field, one would think that he wouldn't give the sonic attributes of SETs (due to their distortion characteristics in particular) a second thought (no pun intended!).  That obviously isn't the case.  This article makes an interesting read and further cements the fact that low power tube amps combined with high efficiency speakers make a winning combination:

    Steve Deckert is also an accomplished engineer whose Zen Triode amp is one of the most popular tube amps out there in its price range.  I rarely see one for sale and have never seen any negative comments about them.  Here are Deckert's comments about why they work so well with high efficiency speakers:

    http://www.decware.com/paper43.htm 

    Lastly, here's a little discussion on an audio forum about using the Zen Triode with Heresys and La Scalas.  It is very informative as well:

    http://www.pinkfishmedia.net/forum/showthread.php?t=159270

    To add my own comments to those above on Pinkfishmedia, I have been involved with a number of SET driven near-field systems using CWs, LSs, and Reference Series speakers.  The result has to be heard with one's own ears.  I can't properly express the musical involvement possible with that arrangement.

    take a look at Susan Parker's amplifier design.

    Very nice, thanks for the link Moray. So many circuits, so many tubes.

    Yup, I would like to see a SS section also. I have a lot of this stuff and I'd like to say my Oppo connected XLR to an Anthem Statement A2 sounds wicked good through my 2 ways. And I would love to see what and how others are using their stuff. And who doesn't like photos anyway?

    Re: Nelson Pass - If he can voice a transistor to sound like a tube amp, just imagine if he sat down to make the best tube amp evar.

     

    Regarding Decware, about a third of the page down Steve convinced me to by the Rachael. I have tried to explain this in my own words but the figures he shows really top it off:

    I was thinking the exact same thing about Mr. Pass but he has commented before that SS is his game.  I believe he has said he owns and listens to an SET amp. He mostly uses mosfets in his Firstwatt amps because of the pentode like curves and his very own Pass SIT's have a triode like curve and he likes to use these active parts with as simple circuit as possible. The one I am listening to right now is the single stage amplification F6 which is a push pull amp. I also own two SE Firstwatt amps. Every one has a different sound. 

     

    My next build is going to be a SET though. Any one have any thoughts about this schematic?

    Where do you find the 8H 150ohm choke and the 1H 50ohm chokes? I have found a 10H  262ohm choke at Parts express and a 1.5H 56ohm. I am thinking the values would work with maybe a R1 resistance change for L1. 

     

    I see beautiful real walnut furniture with a nice tub amp inside! I don't know what it is about walnut. Sweetens my tubes somehow. Makes me want to make some walnut bridges for my cables :D  

    What was your first "tube experience?"

    I thought it was really cool that I could "listen" to my older brothers vinyl with one of my mom's sewing needles. Had to get your head pretty close to hear any fidelity lol.

     

    To this day, he is probably wondering why his albums sounded so bad.

    After your ISP resets your connection and doesn't see a problem from their end, power down all your network gear. Power it pack up after a few minutes, routers first, then switches. After everything is rebooted if it is still wonky, log into your router and make sure your settings are correct, no dupe IPs if your static routed, have a DNS source and do a DHCP release/renew.

     

    If it's still acting up after that check for cabling issues.

     

    Forgot to ask, wired issue or wireless issue?

    Because fixing stuff cuts into profit margins...

     

    It's called "externalizing costs." Instead of actually debugging the software at their cost, they let customers do it at their cost. 

     

    I always wonder how many billions of man hours on earth have been wasted turning little knobs in Miscrosft Windows? And it's JUST an OS! It doesn't even produce anything! Imagine spending hundreds of hours each year rewiring the ignition switch in your car!! Let's make the wires RED now! Let's make the key turn the OTHER WaY~~~ YIPPEEE!!!

     

    lol...ms sucking the life out of the country for 35 years. Folks seem to love it for some reason. Oh that's right, I'm the only person in the world that doesn't own their stock.

    I hear that Win 10 won't allow you to defer updates, as in you have no control as long as your on the internets...

    I read that if you get the pro version of 10 you'll have more say on what is updated and what have you. 

     

    Never played that game either  ;)

    why only JJ ecc803s's work

    Looked up the ECC803 and it looks identical to the 12AX7 and they are definitely listed as compatible. :wacko:

     

    Just a quick SWAG. Don't imagine you have swapped tubes enough in the two years to have stressed out the connectors. Just sounds like a connection issue.

    Just sayin if the pins are bigger on one set than the other set they may stretch the pin contacts so when you switch back the contacts are loose. If you had calipers you could measure the pin diameters, if not just use your calibrated eyeballs.
