But what do they SOUND like vs. stock??? I haven't seen that covered in this thread anywhere.

I woke up early one morning last week, a couple of hours before dawn. I went out to the patio to have a smoke. In the quiet, my mind suddenly raced ‘round the world to Singapore. The thought came very singularly, "Could his system not be sensitive enough to notice the difference ?!". Surely not. It had been a couple of weeks since I had heard from Nicholas. I had sent him a pair of the Philips rectifiers and custom-length cap-wires. Had just been giving him some time.

So I went inside and hit the weight bench, which is now in front of the system. Probably on the 3rd or 4th rep .... my phone alerted to an email. Wildly.

Only just put them in last night.... So far all i can say is: Wow! what a diff! who would have thought rectifiers could make such a diff!

Gonna burn them in more b4 saying anything else. THANKS!!!

Caps, exclamation marks. Almost my exact same response note-for-note. I probably had a little more faith (larger envelope, less heat, potentially greater sound), but there really is no comparison.

Wow, who'd have thunk it! Can you recommend something over the stock ones I have (Svetlanas) For more fullness / bass without sacrificing those sweet highs?

Yep, I stand by my assessment of Ultron tubes 100%. What I said was:

This means nothing in terms of what has been discussed here, but aside from very nice pretty boxes, Ultron tubes are kind of a hit or miss proposition, like the UK brand Haltron, and like Westinghouse in the US - sometimes very nice tubes for a great price, sometimes very average tubes for an expensive price.
And this is absolutely true, and is something that I think everyone should be aware of. I was not making any comment about the Ultron EY500 in specific at all - just that Ultron was not actually a tube maker, and that I have seen people pay a *10 times* too much for Ultron branded tubes that were clearly Russian made. I did not say, nor do I have any clue, as to whether THOSE tubes are actually made in Germany or not.

Karo, those Philips and Telefunken EY500's are indeed nice looking tubes, as you indicated! But other than the ones I posted, I don't have any idea where to get them - Tubeworld was the best source I know of (as I posted above).

I just got this in the mail :
BRIMAR 1 X 6SL7GT VINTAGE VALVE / TUBE BRITISH - eBay (item 260472822382 end time Sep-12-09 11:35:51 PDT)
I haven't really sat with it yet, but initially it sounded really good!
Also, I cleaned off the pins, I found that they are either brass, or gold plated. Can anyone shed some light on this? I didn't know Brimar did that??

Oatmeal, I have a bunch of old JAN brown base Sylvania's 6SL7's you can try. I think you're fairly close to me if you want to grab one.
post #503 of 625
Yeah, I'd love to. I'm in North Redondo, where are you?

I have a Sylvania brown base, green label that is completely coated with Mercury(?) or whatever it is on the inside, which sounds really good - favorite so far, although my first impression of this new Brimar is really good too.

I'm about 5 minutes north of you, right off Aviation, just north of Rosecrans.

Shoot me a PM if you want to borrow something for a few days.

Right ! Well, I've yet to see an Ultron 6SL7 in this thread. The whole way the Ultron name was invoked was dealing with the EY 500s. What I wanted to say before was this .... if you guys had been following the thread you would have seen very clearly what I said, "there is an indication from the supplier that they are Telefunken-made", but he wasn't completely sure. I'm talking about Mattijs' supplier.

In other words, they are made by someone else. I really didn't care. No one else seemed to be bothered by it, or commented either way. So I edited it out when I made a performance update.

I understand that you and David P. are implying I am paying too much for the Ultrons. I trust my sources. Also having not seen David's tubes, I cannot compare them to these. Neither of my 2 sources had any problem with the idea of a better rectifier improving the sound. They both design amps, amongst other things.

I almost sent n_ghows a pair of the Ultrons as well, to let him hear the difference. But I remembered my own initial response. They were worth a hundred to me, easy, in terms of improvement.

We are a nation of price shoppers. If you want to spend 2 grand on an amp and 6 dollars on tubes, that's certainly your decision. Have fun dude.

For me there is no doubt that rectifiers impact sound. I have paid over $100 for rectifier tubes before. And I wasn't implying you were paying too much - just that to understand an Ultron, one has to know who actually made the tube, since Ultron was not a manufacturer.

Just for S's and giggles, here are the Ultron 6SL7GT's:



And lastly, surely you can see that I am the last one who advocates only spending $6 on tubes

Anyway, it's all good, brother. Tube shopping rules, and let us all enjoy it! Peace.

Brimar 3

Super-cool man. Check it out ... this is the second old Sylvania box I've gotten with a Brimar. See the little crown ?! Can't always judge by appearances.











Better than Brimar 1 & 2 combined. That being said .... it's barely holding down the #5 spot.

WOW - nice! I have never been that lucky!
