Tube tester?
I’ve been ’into’ tubes since the 1950’s w my Dad’s Bogen. I always wanted a tester. Many testers don’t actually test in operation range. I considered the µTrace, but it’s more of an engineer or amp designer than hobbyist’s tool. Hence, the tester ... 
Tube amps - what 3 things…
Tube amps tend to be more noisy than solid state Not if they are properly designed and installed.   The world of tube sound is vast and very variable--much more so than the sound of good solid state. Not true. Tube amplifiers are current d... 
Tube tester?
Build your own. I have schematic, parts list, cad dwg and PCB. PM for more info.        
Rell or JL subwoofer?
Nobody mentioned MartinLogan X series. The go low, have full correction. REL ain't what they once were. SpeakOns are a joke for sub connection. Don't believe a word of their malarky. You need to mate sub performance to the mains. A sub needs to... 
Upgrade Cables or Just Upgrade Equipment & Live in Shame?
Try adding just 1 more REL 5Ti Subwoofer and evaluate.   OR try subwoofers with a full set of controls and rolling the lows out of the mains to allow proper integration.    
Never heard an amp do this before, ideas?
There's an Android app NetSpot that will show the level of WiFi RF in the area. Sitting right next to home router is usually about -40dBm. There are relatively inexpensive RF detectors available. The Best RF Detectors for Detecting EMF and RF Si... 
Tube rolling newbie- how to choose NOS tubes
But you would not know if not trying and that is a part of the game. ... of fleecing the uneducated.  
Tube rolling newbie- how to choose NOS tubes
@kennyc   B E F O R E  you do anything, find out what the tubes do in the circuit: do they provide gain or just buffer for cachet are they used in a balanced configuration or single ended if balanced configuration, are they actively balanced... 
Upgrade Cables or Just Upgrade Equipment & Live in Shame?
What kind of cables were they using in the systems you enjoyed?   Irrelevant. Cables interface hardware. Without the same hardware in the same room with the same program, all bets are off.    
Upgrade Cables or Just Upgrade Equipment & Live in Shame?
Coupla points: Swarm was developed to provide even, not necessarily good, bass. Cables, along with everything else contribute the system sound. Change is not necessarily always positive. See ieLogical CableSnakeOil for reasons why.    
Hum in Speakers with New Dedicated 20 amp Circuit
Looking at the photo again this morning of the feeder conduit entering on the left side of the panel it may very well be PVC conduit.   I concur looking at the color, saturation and reflectivity of the visible threads. It's a very close match ... 
Never heard an amp do this before, ideas?
the sound comes through the headphones. Is the sound present on all inputs? Does the level change with the volume control?  
Never heard an amp do this before, ideas?
Do not EVER turn on a tube amp without a load. Misery is guaranteed. Depends on the amp. A stable amp can be on but not driven without a load.  An unstable amp may be a problem with or without a load.  
Never heard an amp do this before, ideas?
I have svs speaker cables, but it happened with headphones and no cables too. Does the amp have a headphone jack and you hear it with headphones and no speakers attached?  
Never heard an amp do this before, ideas?
Does it happen on all inputs of the integrated amp? What happens with a shorting plug in the inputs? What happen with a shorting plung and the speakers disconnected? You will have to measure with a scope or good multimeter/ What are your speake...
