@Deleeh Just received my tubes from Langrex , 1 GEC KT63 is dead on arrival and 1 6K6GT Visseaux has a broken off getter and doesnt work , I think their quality control needs some work but luckily their customer service is excellent
Oh, I'm sorry to hear that.
Looks like Langerex didn't get a good Kt63 Gec from the stock they bought.
My first couple of Blackglass one of them was quiet and cracked shortly after switching on.
The 1st replacement pair one tube was dead and didn't work, the 2nd replacement pair both worked but were slightly different in height.
I bought another pair on Ebay from a private seller who still had some for a good price and the pair was fine.
In total I now have 2 working pairs.
Maybe a 3rd pair that is mixed where one tube is black glass and the other is smoked glass.
I still have to try it out.
I am surprised that the Visseux is broken, you should have seen it before packing.
A check before despatch at the latest would be the minimum, but as the service is still good I trust Langerex.
But in fact they could take better care of it.
I think it's a bit of a bummer that you don't get any measured values from the tubes for the matching payment.
I hope they send you a replacement soon, and above all that they still have a few Kt63s.
Otherwise I'll be happy to give you the link to the other Kt63 I bought on Ebay.
