The white thing in the back circulates Freon to keep the temperature down?

That's a beautiful set up you have there, thanks for posting that as I'd been curious for quite some time now.

Telefunken E88CC

Nice looking. I have one, just one Telefunken, but some 25 Amperex Bugleboys, including some PQs etc.

Got hundreds of used tubes, including new caddy with NOS in them.

What to do with them all.

Cheers.

Adrian,
What tube gear are you actually using?
Inquiring minds want to know!

Sorry Steve,missed your post,showed my gear on #509.

27 pages of tubes and not a single nuvistor in sight...

Apparently they were not used much in audio gear except for studio applications. From Wiki:

"Nuvistors are among the highest performing small signal receiving tubes. They feature excellent VHF and UHF performance plus low noise figures, and were widely used throughout the 1960s in television sets (beginning with RCA's "New Vista" line of color sets in 1961 with the CTC-11 chassis) and radio equipment and high-fidelity equipment, primarily in RF sections. They competed with the solid state revolution, and along with GE's Compactron, probably held it at bay for a few years. RCA discontinued their use in television tuners for its product line in late 1971. One famous application was in the Ampex MR-70, a costly studio tape recorder whose entire electronics section was based on nuvistors. Another limited application of this very small tube was in studio-grade microphones from that era, the AKG/Norelco C12a, which employed the 7586, being a good example. It was also later found that, with minor circuit modification, the nuvistor made a sufficient replacement for the obsolete Telefunken VF14 tube, used in the famed Neumann U 47 studio microphone."

I do remember some company (Music Fidelity maybe?) coming out with a Nuvistor amp and pre made with surplus tubes they found. They were all over Audio Advisor about 10 years ago. Who wants to look at pictures of those 'tubes' anyway?

Beautiful stuff! What are those tube amps? I'm not familiar with any of them. And what's that in between your AR components?

Hi Ericus Rex,The bottom one is a Leak 12.1 and the Matisse Fantasy Pre-amp on top.

JakeJ · « **Reply #531 on:** 16 Jun 2013, 02:08 pm »

Ericus,

You are correct about the Musical Fidelity designs. They are still out there and the limited run was due to the limited supply of tubes available. I believe they did keep a small supply of tubes for replacements. There is an MF Nuvistor DAC available right now at Echo Audio in Portland, OR for a reasonable price.

I wonder how these sound:

http://www.ebay.com/itm/2x-6E12N-V-6E12N-Nuvistor-type-Metal-ceramic-HF-POWER-AMPLIFICATION-SOVIET-TUBE-/310395062476?pt=Vintage_Electronics_R2&hash=item4844fcc8cc

$9.50/pair and capable of 2.2 watts. States Hi-Freq voltage and power amplification though. Might not work for audio freqs. Is 50mV of noise a lot?

LeeH · « **Reply #533 on:** 16 Jun 2013, 04:10 pm »

Not the best pic but boy oh boy can this amp boogie, 20w of single ended valve loveliness.

Ericus,

Good question. At 2.2 Watts they might even drive a set of headphones directly. 50mV is a bit high but with the right power supply it might be reduced by a factor of 10.

B65,Six Versions
Three Grey Glass
Three Clear Glass

Grey Glass.Top round mica with rectangular getter,Top round mica with pan getter,Top round mica with edges and pan getter.
Clear Glass.Grey round edges top mica with round bottom mica.Transparent top edges mica with edges bottom mica.Transparent top edges mica with round bottom mica.
To me,the best sounding version is the Transparent top edges mica with edges bottom mica. Sounds transparant,excellent separation and extend high, they remind me their stablemate B309 which

sounds exactly the same.
