Does Jack make adapters to take the 6DE7 drivers to 6SN7's? Just curious.

Hi Koven

I got mine from a US-based head-fier earlier this year. I havent seen any come up on ebay at all. Perhaps Woo audio or one of the reputable tube sellers in USA can source a pair of Raytheon 6ew7 for you.

Thanks I will ask Jack.

hi, do you mean an adapter to use 6sn7 on the wa6? if so, i believe jack
sells them now. don't know what he charges though.

hi a, i hope all is well in your part of the world. yeah, ebay is not the best
source to buy the 6ew7 now. they are sweet tubes and should last years
if treated right. but the 6sn7 is even sweeter with some depth in the music
and a larger sound-scape. better tonal balance and a refined/delicate mid
and highs on the wa6.

Hi, yup. That's what I mean. Already e-mailed him. Just waiting for a reply.

I emailed him last week about the adapter. So far I haven't heard anything

Hi Takezo, all is good down here thanks except for District 9

Hope you are keeping well.
Nice to see Jack is making this adaptor available, thanks largely to your tube-rolling experiements.

Do you find the 6sn7 to offer noticably improved performance over the 6gu7 or 6fq7 (which I have read are based on the 6sn7 tube) in any areas?

hi a, initially i really thought the noval based 6gu7/6cg7/6fq7 were on par with
the 6ns7 family, due to their similarities electrically, but after having tube-rolled
for the past year on the wa6 and wa6SE, i'm clearly in the 6sn7 camp. on my
set-up the 6sn7 offers a wider sound-scape, more refined tonal balance and
transparency on a higher level than the 9-pin bottles. but they are about 1/5
the price of a NOS 6sn7 tube and very close in SQ as well. but the 7n7 takes
the cake for me. they are on par with the best of the 6sn7, except the exotic
ones i haven't tried, at 1/4 the price. the 7n7 needs a different adapter than
the ones for the 6sn7 due to difference in pin layout.

Thanks for your valuable comments Takezo, looks like my driver tuberolling is far from finished

I'm just hoping I'll find a Sylvania 6FD7 that works, the brief time I got to listen to my last pair sounded beautiful. I should have a pair of RCA 6EW7 to try soon too

 

[musicmind]

Covenant, I've only tried the RCA thin bottle 6fd7 which worked quite well, no unwanted noise (I have the WA6 though, not the WA6SE like yourself). The increased gain as others have commented, was noticeable. However the detail and more open sound of the 6ew7 (the Raytheon in particular) was much more to my liking with the music I listen to. For bass punch and more dynamics, the 6fd7 is nice, but the Tungsol 6de7 edges out the RCA 6fd7 in the tight impactful bass it provides with my HD650.

I'm guessing the RCA 6ew7 will sound a bit warmer than your Sylvania.

Openness with detail and dynamics are the traits I'm predominantly looking for at the moment. I had a set of fat-bottle Sylvania 6FD7s that seemed to be very good at this, but the set developed cracking noises and had to be returned.

I've got some small bottle RCA 6DE7's in at the moment which sound very nice, too. But they're slightly noisy.

Is the RCA 6EW7 a good upgrade from the stock 6ED7's? What are some other options?

I think it depends a fair bit on what headphones you use. Atm I have the small-bottle RCA 6DE7s in and actually prefer them with the HF-2, as the slightly decreased soundstage and increased dynamics seem to synergise well with them.
