Anyone ever have, use or hear this tube?


I always thought that the pinnacle of the ecc82/12au7 type tube was the Telefunken ecc802s. Even better than the Amperex 7316. But, I recently found out that there is an extra special designation for some ecc802's dubbed the G73R. These are supposed to be unmatched in quality and longevity, said to last 40,000+ hours! Anybody familiar with, heard or own these things??

@wharfy ...reminiscent of ee cummings, actually......waiting on taking a 'breath', so to....type... ;)

Not here to judge....just edu-lurking anyway....

@wharfy, i dont know what the real price of these tubes is, but tubedfepot.com typically sells at 2x-4x the legit retail price and even buy from retailers, just like any end-user, and jack up the price. their testing is minimal. theyre great for new production, especially for guitar amps, but for old stock their preice gouging and minmal expertise is a last resort. they also mis-identify OLD stock tubes, making basic mistakes like asserting that philips-labelled EI yugoslavia tubes, of which they sent me several pics clearly showing EI yugo codes,  are really philips. https://www.tubedepot.com/products/7dj8-pcc88

after i informed them, they made no correction. 

for old stock tubes, the big three are brent jessee, jim mcshane (mostly retired), and andy/vintage tube services. andy takes a very, very long time, but hes quite strict. 

there are some excellent second-tier dealers as well, like tctubes.

Good info. I did not know that. TY!

Anyone remember when "Tubes" was a very, very active category on A'Gon? Pages of NOS offerings. Today, I saw 29 listed.

I have found the Mullard CV4003 to be about the most balaced of the bunch. The romantic tubey blush with very good resolution. Another under the radar small signal tube that is equally great (depending on the component used in) is the La Radiotechnique 12au7wa - never imported to the US but a few retailers and specialty shops have had them in the past. I use them in my DAC - thy are spectacular. Just my opinion
