It’s not my story to tell, but I would be surprised if he would be at Decfest, although I could be wrong. If he doesn’t respond immediately be patient with him. My thoughts go out to him and wish him the best.

I still have a long way to go. Sitting in the high 500's on The List(TM).

I fell in love with the EML 5u4g Mesh plate. It is the sound I want. It's also a super sexy looking tube.

EML makes a few different versions of the 300b one of them is a mesh plate version. It was designed for low anode dissipation.Is this tube is compatible with the Sarah 300B?

It has a recommended anode dissipation of 22 watts and a maximum of 28 watts.

Based on the last post I saw from Steve Sarah is at 28 watts and change. So, I guess the question is do you feel lucky? Of course contacting Steve would remove the guesswork.

Well shortly after I turned the amp on Monday one of my Sophia Electric Classic 300B went silent except for a hum. Didn't take out a fuse or impact the amp in any way, but I was down to one channel listening. I brought out the headphones. . . .

I contacted Sophia Electric and as I had a demo pair that was not offered with any warranty (at a big discount) I was out of luck. I figured these were demo tubes and should last longer than . . . 700 hours but that is about what I got out of that tube. They offered to try to match another tube for me at the same price (half the price of the pair) and I may take them up on that but that was going to take time and damnit I wanted to listen to music. I have a pair of Cryotone 300B-WC on order but on inquiry I can't expect those til they maybe ship next week. So. . . I ordered a rather inexpensive pair of Psvane 300B HIFI tubes, I think their lowest model.

Those arrived today and I'm listening to them now. Honestly they sound decent. Not quite as good as the Sophia Electric so far but they're also not broken in and I'm so eager to listen to speakers that I am cutting them some serious slack. Ah. I'm listening to the amp again, and that's certain happiness.

I'm looking forward to testing the Cryotone 300B-WC. If they don't knock my socks off I'll return them and order a pair of WE300B. But I think from what I have read from Steve, et al here that I'll be happy with them.

Til then I think that for about 260 a matched pair the Psvane HIFI are a good backup pair.

Lon, Sorry about the Sophia. It's been my experience that Psvane tubes sound very underwhelming when new, but really sound great once they reach their break-in point...so much so that there's no mistaking when they are or aren't broken in, lol.

And yes, I too go through serious withdrawal symptoms when I'm unable to listen to my Sarah... Smiley

Pretty sure there's a support group for us somewhere..."I'm Michael, and I'm a Sarahholic".

LOL! Well, I'm liking the sound of these Psvane right now, so if they improve that's great. (Of course with the ZBIT and the ZROCK2 I can make mediocre sound become much nicer, man I love these components.)

I actually enjoyed the headphone use. I put my trusty old CSP3 into the system that Steve built with a glass resistor bypassing the input gain section and with the full Anniversary mods--with the Sennheiser HD800S and the ZROCK2 this makes fantastic sound that transports me. But I was eager to get the SEWE300B going again, it's a special amp, it has really seduced me. My wife likes it too, more than any other amp I've played the last 9 years we've been together. . . but she's a bit jealous of how it pulls me off to listen.

I think Steve will be building and building these. They're going to call to many.

So now I have the Cryotone 300B-WC broken in and also a pair of Takatsuki 300B to check out thanks to James.

Both are excellent tubes. . . my untreated room and system seems to prefer the Cryotone as though I don't find it has the extra bass that others report, it has more than the Japanese tubes and it has a density that I had grown so used to with my SE84UFO3 Monoblocks.

Oddly I think the best tubes for my system may have been the Sophia Electric 300B Classic, but one failed so early that I haven't sought another pair. Those had an extra richness that suited my less than stellar recordings (the bulke of my big collection) more, a bit more forgiving and warm.

I have decided that I like the Cryotone tubes now, those three that came with the CSP3 that I bought from JOMAN are as good as my nicest 7308s, and I'm breaking in Cryotones for the ZROCK2 and the input position of the SEWE300B that are showing promise. I started off wtih the 6SN7 and that seems a mistake as that Cryotone pair I could not get to work in my main system, and the Cryotone 5AR4 I got with the CSP3 from JOMAN I didn't like at all either. I'm waiting on a pair of the same in the CSP3 for the driver tubes on the SEWE300B to see how that compares to the 7308s I'm using there.

Overall I'm truly enjoying the SEWE300B with whatever tube complement I use--it's a fantastic amp.
