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.

Just make sure they don't say Svetlana,unless they are old stock.Those (the real original)usually are available in a used
amplifier for sale.The new one is supposed to be the same tube.They are called the Winged "C" SED.They have the same welded plates as the old. The New Sensor copy has 4 hole punched through each end of the plates like Sovtek,EH,Svetlana
copy.I'm on my last set,but have not bought any for ?? years.
I'm not familiar with any new dealers.If they look like your EH's,they're copy's.Link for real ones >>>>[http://thetubestore.com/el341.html] copys link >>>>[http://www.zzounds.com/item--SVEEL34]ZZOUNDS link is copy.Tube store shows the real SED,the preferred.
Excellent ,reliable tube..Check again at tube depot..I bought mine there...Looks like they still have them .........$50 pr......I have bought at least 4 quads from them ..Never a problem...Great sounding New production El34........

place.Real Winged "C" tube. the original preferred.Link>>>>
