SED Winged C el34. Help


I am tube rolling my Manley Snappers. I have heard many good things about the Winged C's. I have a few questions.
Are they reliable? I bought JJ el34's and the were like hand grenades in my amps. They blew and took out the tweeters and the woofers in my speakers! Ouch.
So I went to the EH 6ca7 at Manley's suggestion and they
have been reliable. However I would like to try the winged C's, but not at the expense of my speakers.
Also, where do I buy them. I saw a thread that said not to get the Svetlana version so I want to make sure I get the right tube. I have shopped at Tube Depot before but they don't sell them. Upscale Audio does but I have seen them for less at other dealers. Can you reccomend a good dealer?
I would also like to hear from those with experience with these tubes as to whether I can expect an upgrade over the 6ca7's.
Thank you, Scott.

They're fine. Great. No problems. I have two sets of 4. 16 total.

AES. Antique Electronic Supply. Tempe AZ. They sell the real deal.... or did a year or so ago. About $20 ea or so, and they'll or used too, match 'em too if you want... it is extra.

Thanks for the note on JJ
Excellent tube if it is the one manufactured in St. Peterburg. New ones are only labeled as Winged "C". I have used a quad for over two years without a problem and they hold a good solid bias. The Tube Store is a great source or Jim McShane is another that burns them in and matches the pairs or quads prior to shipping.
I am also using the Snappers and at the time being have the EL34 SED Winged C bought from tubedepot.com. I do not understand what you mean by not buying the ones from Svetlana, cause is it not Svetlana who makes the new production of SED Winged C?

Anyway, I am satisfied with the SED version. No problems with them after several months. In my system they took the sound one notch up from the Manley factory tubes. They makes my system even more transparant, dynamic and with a tighter bass.

As Blindjim says; thanks for the note on JJ. I have been curious about them, but think I will leave them for others to buy.

Hope you post your experiences. It would be nice if this thread could be a place for exchanging experiences on EL34 and Manley gear.
