Thanks for the reply Marty.

What kind of tube tester do you own? I need to get one but haven't decided. I like the amplitrex but it is 2,550 dollars. It does hook to a computer and it comes with software. Which it should for that kind of money.

I saw you mention the other tube types. Does a 12DW7 have the same gain as a 12ax7? Have done any testing on a mullard 10M 12ax7. I was told the are nothing special.

As far as Eurotube goes, well I know what I was told. I also know what I read on his website back then which I don't see now. He said that he had done extensive testing against all NOS tubes and that the JJ's sounded just as good if not better.

I also see a tube seller on ebay that just by coincidence comes from the same place Eurotubes is. I also talked with the tube reseller that is recommended on the THD univalve forum. His name is Mike. He owns KCA tubes. He sells some of the JJ's. I asked him why he didn't sell more of them and he said I only sell good tubes. When I asked him what was wrong with them he said there were batches of tubes where he rejected 75%.

I am sure glad I stumbled upon this forum. I also own a line 6 vetta. I am a member over there. Or should I say what is left of it over there. I remember when I got it. I had it set up next to my tube rack rig, which sounds great by the way. I remember thinking what the hell did I do. I couldn't take the vetta back because of where I bought it. But I forged ahead, I actually got that thing to sound pretty good. But only because I could A/B it against a real tube rig. I remember telling the members of that forum my experiences and I got flamed and burnt to a crisp. You would have thought I was criticizing their mother. I told them how do you expect an amp that is trying to sound like a tube amp. Or in this case many tube amps. How do you expect it to sound better than the original.

I still have the vetta. It is good and very versital. I am glad I have it and it makes a great practice amp. I spent alot of time tweaking it. ALOT!!! Out of the box it is not good. Maybe the newest software is better. I don't know. And I am not going to find out because who cares. It will always be just an imitation of the original. It is probably the best amp if you want to be in a cover band.

Needless to say they didn't like me over there. Now the funny thing is they are almost all gone and have went back to tube amps. What a laugh!!!

Some people are pathetic. They will never admitt when they have made a mistake.

I have alot of testing to do. Marty, what do you think of telefunken 12ax7's? That is supposed to be a favorite of marshall amp people.
