No mesa didnt relable the true siemens 450's. What they did was send you the next available el34,, the 447.
Just this past Monday I called Mesa directly because on their web sight they still offer the 450's. The Gent I spoke to looked into it and indeed comfirmed that they are no longer made and not available. Why havent they been taken off their sight is beyond me but I never asked either. I also have a hard time picturing mesa actually knowing they are sending the wrong tubes at NOS prices. But you never know.
The same day I spoke to mesa I looked on their sight and called every one
of their listed dealers in my state to see if any of them had any remaining 450's in stock. I called every dealer and only one of the 8 places I called actually had a duet of 450,s he found at the very bottom of a stack of 447's.
I didnt buy them because I need a quad.
So think of your situation here,, on their sight they offer 450's,, you bought them but they have no more. Instead of contacting you to say they no longer supply these,, they simply take a couple 450 boxes and put the only available el34 in them that they have,, the 447.
Id bet if you contacted mesa they will tell you that they are all pretty much the same,, try it.
And to make matters worse they stupidly only put 7 tubes in an order that obviously was 2 quads. Remember, they sell individual tubes and duets and el34's are not available as individuals so how can the actual order come out to a total of seven?
I love my mesa I really do but from what ive been reading on many forums mesa is deffinatley starting to cut corners.
And to make matters worse I know for a fact a thread was started here on this forum about 6 months ago about this same subject of 450 NOS mesa tubes. A few of the posters on that thread also called mesa and confirmed to the rest of the people that they were in fact out of stock and not able to aquire any more. I knew this many months ago but upon browsing the mesa sight months later I see that they still offer them so thinking they may have indeed found more, I called them directly and was told they were not available anymore just like the other posters were told months ago. Now why would a top notch company simply not update their sight to stop the confusion? Somethings a bit fishy to me.
