Tube rolling 6922 tubes looking for transparency
I've been using Siemens CCa's(from the late 50's-early 60's) for a number of years(six in my CDP, lately), because of their transparency, frequency extension, bass accuracy and sound stage abilities. The CCa was a specially selected 6922 family tu... 
Best Alternatives to Black Gate Caps
Parts Connexion still lists a 3.3uF, 50V PK Black Gate on their site(click on Black Gate, bottom of page). (http://www.partsconnexion.com/t/catalog/CapacitorsElectrolytic.html) I wish Sanyo would produce their OS-CONs in higher voltages. 
Is this clipping or just high SPL?
Perhaps it was a stretch when I assumed most understood; a single classical guitar, a small chamber group, an acoustic jazz or blues set, through Heavy Metal bands or philharmonic orchestras playing fortissimo(ffff) all produce, "live" SPL levels,... 
Elusive Tube-Amp Hum
As Mr L mentioned; the problem could be a cold solder joint on a ground connection, or a loose ground terminal on one of the RCA jacks. That the problem didn't occur at the shop, without your interconnects, does make them suspect as well. Cheaper ... 
Is this clipping or just high SPL?
DJ- To answer your question: YES, reflected sound/loud mush at the listening position. As an experiment: find two or three large, thick comforters and drape them on the wall, behind your listening position. That should let you know if slap echo is... 
Is this clipping or just high SPL?
My listening room is also somewhat small. I found that, at anything approaching a realistic(live or monitor) listening level; the room was overloaded. Treating the back wall(behind my listening position, about 2/3: top-down) with 3" Auralex and LE... 
Used tubes question
Those that don't experiment with NOS tubes, just don't know what they're missing. Enjoy your music!! =8^) 
An honest opinion about upgrading?
IF the volume levels which you are obtaining are satifying to you; much of the improvement you desire can be had via NOS driver/phase splitter tubes in your power amp. For definition and clarity, I'd personally recommend a pair of Siemens ECC83's,... 
Why 6H30 Tubes?
(http://www.balanced.com/) Click on, "The 6H30 Tube - One Designer's Perspective" for some info. That was dated before the tube was readily available in the market. I still personally prefer the upper crust of the NOS 6922 family(ie: Siemens CCa o... 
Used tubes question
Finding TungSols in matched pairs will be hard to do(no- I can't cite a good source), but worth the effort if you can locate some that are low enough noise for a preamp section. Depending on what half wave rectifier you are presently using(ie: Chi... 
Ideas for used SS amp
2nd the Hafler suggestion. ie:(http://cgi.ebay.com/HAFLER-9300-AMPLIFIER-AMP-1200-WATT-HOME-THEATER-MOVIE_W0QQitemZ230373733135QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item35a358330f&_trksid=p3286.c0.m14) The DH-500 will drive you up a wall ... 
Foam Plugs
It would be nice to know what size woofer you're talking about. The last drivers I shopped for were 10", and that's been a couple years ago. I couldn't buy the drivers that Lyngdorf used in their W210(raw) or anything equivalent, so I stopped shop... 
Live equipment chassis
Actually- The nation is becoming more Socialist by the minute, in case you haven't noticed(are you a blond, by chance?). Funny, how little sense of humor Liberals have!! BTW- You're quite welcome. 
Foam Plugs
Mr T- They laughed at Bob Fulton too, when he'd walk into a shoppe with his 'Gold's'. The laughing stopped, when the music started. Look at the revolution in cables he started. Mr E- There are a few drivers available, with fairly long throw voice ... 
Live equipment chassis
Think of the income potential, equipping all those squirrels out there with miniature Faraday Cage suits. I'll bet Obama and the ASPCA would finance it! Well- It would end up coming out of taxpayer pockets, but........
