@jetter According to our warranty policy, tubes can be returned or exchanged within the warranty period. If you encounter any issues, we can provide assistance.

And we will also investigate the after-sales rate of tubes from Viva to identify the exact issues in the transportation or production process. 
We apologize for any inconvenience this has caused you.

6L6 and KT66 can be interchangeable in certain situations (depending on the amplifier you are using). Our Horizon series also includes the 6L6WGC-AT.

The bias voltage requirements for KT66 and 6L6 are different. When interchanging them, it is necessary to readjust the bias voltage to ensure the tubes operate within the correct range. If the bias voltage is incorrect, it may cause the tubes to overheat or distort.

It would be nice to have a real KT66. :-)

I have used PSVane tubes for two amplifiers, both in preamp and power sections. They are very good quality. It is a big advantage to be able to get matched sets easily rather than relying on NOS suppliers where matching and even availability are uncertain.
