6550
6550 SED winged C are difficult to find in decent prices in Europe, I shall wish knowledge so certain of you tried quartets of JJ, EH,Sovtek or other brands on their amplis CJ in particular on the LP series
thanks in advance friends

Yes, Philippe the winged C's are hard to find.
I am using Tung Sol reissues in the prem 8a's and they are excellent. perhaps not quite as dynamic as the Svets, but very good |

+1 on the Tung Sols I use them in a CJ 11-A they do not seem to have the bass of the winged C's but I actually preferred the sound of them in my system overall. My winged C's are sitting in the tube case resting.
I am now trying a set of Gold Lion KT -88's and liking them maybe another tube you might try. |

Tungsols.
I actually prefer them to the Gold Lion Kt88 at least in so far as I cannot tell much difference and they are about 1/2 the price. |

I am surprised noticing that at my supplier the Tungsol KT120 is less expensive than SED 6550 C logo

Here is a reply from a friend at CJD to my inquiry about the KT120s:
Ed passed this along to me. We have been very much taken with the sound of the new KT120 tubes. Sound quality is even better than our earlier favorite, the "winged C" tubes from Russia. The KT120s are a plug-in replacement for the 6550s on all of our amplifiers. They have higher voltage and dissipation ratings, so should prove extremely reliable (though it is a bit early to be sure of that). The power output of a given amplifier will not change when the KT120s are substituted for 6550s. They are capable of being run for more power, but only if the amplifier is designed for that (higher plate voltages and a different turns ratio on the output transformer). But this means that they are being run very conservatively when simply replacing 6550s. Aside from catastrophic failures (arcing or short-circuits), I find that output tubes often are good for about twice as many hours as the more critical input and driver tubes (as long as not operating with disastrously low impedance loads - no worries with your Wilson speakers), so should be good for around 3000 hours. When the time comes to replace the outputs, I would definitely switch to the KT120s. Bob |

Glad to provide the info. Think I'll order a set for the LP140s and deal with the tube cage issue when they get here.
Hope you're feeling better. Bob |
