Quote: Of all the CCa S&H's I have had which is over 40 + sets I have only had one or two sets extremely microphonic I will say something to twist your noodle a bit since I saw nightflight mentioned me .. I feel special I am still remembered HAHA.  Anyway microphonic tubes may not always be...

Haha I was messing with ya man being a analog component much like some capacitors that I have seen a change in over time pretty much proven.. I would agree some amount of time on the Audiophile front is prudent.. Now for Preamp tubes same situation we have with the Lyr different tubes really...

HK you know down deep inside I love ya, but please explain one thing to me. Where does this magical 100 hours come from for a tube breaking in? The reason I ask is I have seen no return whatsoever over 8 hours at top. I mean I deal with huge EL34 tubes 6L6s and I just do not hear it at all.. I...

Yes we do possess these I love my many sets I will hold on to them and retire some day haha :)

Quote: My Jesting with you was all in good fun my only beef at the time was simple I would get 20 private messages asking where they could find the Lorenz that we all love you and I well know these tubes are like needles in a Hay stack if you understood that I had to answer ohhh over 40...

With Tube amps of all sorts it does not matter if you run them with lower voltage in the Lyr's case that would be 6.3V now it may not sound good or it may have no impact the Lorenz Stugarts one of my favorite tubes is I think 7 volts --- A real world example is - I usually manually under bias...

Ohhh my you guys are stouting the Amperex Oran as good sounding tubes?... dear  they sound ok but pale in comparison to just about anything but he bottom of the barrel.. This thread has gone to hell....   Glad I was active when we really had a consensus on what good was... god you guys...

Quote: What did you pay if you don't mind me asking? I do not use tubemonger accept for the Lorenz when they were around I bought a huge amount.. just curious or nevermind I am tired I will just see if they have any.. I think the funniest one I have seen is some guy on ebay that for like...

Quote: YOu are 100% correct on these tubes the Simens E88CC's made in the 70's are horrid sounding so bad that I have never been able to get them to sound good.. However, I have a set from the early 60's and they are totally different sound similar to the CCa's but without as much 3d...

Quote:   The differences are in this thread however, hidden and I myself never updated a very old list of tubes. Just an idea because every persons equipment is different. The CCa Simens & Halske have an incredible 3d sound stage with the right equipment sadly they are a tad shy on bass...

Quote: Trance_Gott   To explain to you why the hissing went away is simple when tubes get  shipped around they are analog devices tubes get  moved around the getter get's shaken up.. After usually 6-30 hours of burn in time is typically goes away. Now this is a known issue and is on...

Dear me now we have people not understanding tubes.. and whining and they confuse themselves due to just being dumb Wow! And blaming others Paradoxer I feel for ya... I have been there...

The Siemens E88CC  have tremendous bass but they are vintage tubes if you are after great bass you wll surely either need to change something in your signal chain or start spilling out the cash for Vintage tubes.. The Lorenz Mica's also have tremendous bass if you can find a pair.. Their are...

Quote: This is a common problem with all tubes even brand new they can be bad from the factory this is not brand dependent. Firstly no one will want them if they are hissing that is a sign that one will be go out how long who knows there is not gurantee with tubes. Now consider the fact...

Quote: My take on this tube is simple variable Mu, high distortion characteristics, was used as a UHF radio tube just throws so many red flags I would never roll it even if they are dirt cheap...   Sadly at the same time you can once in a purple and pink moon find tubes that are the...
