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??
Don't know about the 12A family, but I did a bit of rolling when I had an ARC SP10. Very good were Telefunken 6902, but standard T 6902 were almost poor beside the Telefunken 6902 specially selected by HP. They came with both T and HP seals. Rumour in 1970's LA was that engineering co-op students spent a lot of time at HP testing tubes, discarding more than 95% to the dumpster. Which explained why HP want 10x the price for their tubes. |
Yeah, anything labeled for lab equipment and such used the tested cream of the crop. And you pay for those little letters and stickers! You think you’re the only one with tube knowledge and experience? I’m well aware of where nos tubes come from. They are what I research and buy exclusively. I’m also aware of the common ones, the rare ones and the ones in between. I’m aware of the applicable prices. I’m also aware of reputable companies that sell them, tested, matched, and readings confirmed with a print out. Although I appreciate you taking time to post, your blunt, rigid statements leave a bit to be desired. |
@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 |
