Altec Lansing A7's 50's model
Here's a link to the system's PDF manual: (http://www.altecpro.com/pdfs/vintage/SpeakerAndMics/systems/A7-8G%20VOTT%20Speaker%20System%20Manual.pdf) and these guys do the authorized repairs: (www.greatplainsaudio.com) 
Altec Lansing A7's 50's model
Altec still supplies parts(diaphragms/woofer re-coning kits) for the drivers to all their authorized repair/warranty stations. Waldom Electronics supplies re-coning shops everywhere, and parts that will make the woofer LOOK original, but it will l... 
300b amps bettering the midrange of the Cary 300b
Mr F: Regarding caps in the power supply(like that 1000uF): The more capacitance, the greater the dynamic range/headroom of the amp. If I were going to mod the power supply: I'd find Sanyo OS-CONs(http://www.diyparadise.com/oscon.html) of the same... 
300b amps bettering the midrange of the Cary 300b
The output transformer's low turns ratio(8:1), it's quality and circuit simplicity of the Cary will always keep it in the lead sonically(WELL- someone is certain to outperform it eventually, BUT-at what cost?). In these forums you'll find a lot of... 
sweet, euphonic, reasonably powerful tube amp?
You might also look for amps that are built with oil/paper caps in the signal path. Those lend the sound that you are searching for as well. 
sweet, euphonic, reasonably powerful tube amp?
Funny- I've been rolling NOS tubes in my amps for decades without one issue. Happy searching! 
sweet, euphonic, reasonably powerful tube amp?
What 6550's are your using in to VT-100? Some are brighter than others. have you tried lowering the bias slightly? That will also take a bit of edge off. If the amp were either the MK I or II, I'd suggest rolling the 6922's into a Mullard or Brima...

Enjoy your music Mr J! 
Best 6922 tubes for BAT VK300x ???
Not a problem Mr Z. When I got my last ones, four came from W. Germany and two from Argentina. They've functioned perfectly for me. The seller of the pair I showed you posted complete specs, and good pics which are confidence builders in my book(o...

AH- Something else I forgot to mention about the CCa's: They are a 10,000hr tube(as are the E188CC's), which makes them a bargain with regards to longevity and musicality. You'll note the writers that say the CCa is "too thin" never mention the vi...

By all means follow the advice given by Mr PTM! That wisdom has been around for as long as I've been in audio/sound reproduction(over 30 years). NOT ALL NOISE IS CONSCIOUSLY AUDIBLE. That's why the differences power conditioners make are sometimes...

BTW: Should you choose to go with tubes other than the CCa's, which were factory screened/selected for low noise already: Be certain that whatever you get is certified pre-amp grade. Any tube noise will be magnified exponentially if used in your B...

That estimation of price for a pair of CCa's would be correct. I've got six in my BAT VK-D5, and they were worth every penny. When a tube can affect the equivalent of a major equipment upgrade (vis-a-vis musicality): I'd have to say it's worth see... 
Best 6922 tubes for BAT VK300x ???
I should have mentioned: If you do consider the CCa- Make certain to buy NOS from the 60's, with the dull grey plate beneath the getter support. If it has a shiny plate, or date code plate inside, it's from the later production and will singe your...

The "best" are the Siemens CCa's. Their E188CC/7308's are no slouches either. Of course- Telefunkens are way up there on the list also. We're talking transparency, extension(both directions), dynamics, liquidity, imaging and sound stage(ambience r...
