You are lucky man for no need to travel frequently, I need to go to my Shanghai office every alternative week and stay there from Mon to Fri every time. My wife has no hard feeling about my travel and she says, she feels nice home alone with my cats when I'm not home.

For all the dedication you have and the commitments you keep (home-work-audio), you are truly noble, dannie01.

Sophia's 6SN7 should be OEM by Full Music which manufactured in Tianjin, China.

Unless you are madly in love with the looks, I wouldn't bother.


I like the looks but definitely not enough to make a purchase. One of my fugliest tubes is one of my best bang for the bucks, that Brimar 5Z4G rectifier. I guess you said it all a couple of years ago re the Sophia Skylab, thanks again.

It looks like Skylab tried them a couple of years ago and liked them for the most part, just wondering if anybody has used them is a Woo more recently.


One person likened them to the tung sol mouse ear, citing very similar tone.  There aren't a lot of impression on them in general.

Fellow Woo'ers, I need some help.  I'm looking for a person who owns a tube tester who would be kind enough to test a few tubes for me.  I nabbed some Chatham 6AS7G tubes off eBay for cheap, but the only information posted was that they "test good" with no details.  I received the tubes today, and to be honest they look scary.  The bases are slathered in some type of glue in a really misguided attempt to solve a loose base issue with the tubes no doubt, but they really got it all over the place on them.  I got them cheap, so there was little real risk, but I'm hoping to actually test them and find out their Gm readings to see if any of them make a proper pair and to know that they test good for shorts and leaks.
 
If anyone would be willing to lend a hand please shoot me a PM.  Thanks!

Good things come in ugly packages, the beautiful EML 274B tube is resting peacefully in it's supplied box (coffin?). While the ugliest and smallest rectifier I have (RCA 5U4GB) gets all the loving. Though I expect my new favorite will be the SYLVANIA GB 5931 that I will be getting soon. 
 
And talking about the SYLVANIA GB 5931, any opinions about it? My hopes are it will be like a souped up RCA 5U4GB :)

I think the Brimar is pretty cool looking myself.

I think it is a beautiful tube. "ugly" is just a cute reference to it. I really like the fact that you can see the other side of the tube by looking right through the 4 holes on the front plate and through 4 more holes through the back plate.

It looks like one of ACME's very first Rat Traps circa 1941 , merely enshrined in glass for the company's history and preservation. Truth be told, your Silver & Elegant Woo can make a many a tube look good.

I just have to show this cool/weird looking tube. Here it is, i wish there was a video on it...



That is a small 2" picture tube 2AP4 used for oscilloscopes. I have some of these that I was going to build into my speaker amps to look at the output wile the amp was running.
To tell when I was getting close to distortion. But I decided not to go through the bother when I built them.
