I want to try KT66's

[Nathan]

My amp is an Allen Tonesavor 80 watt BF Twin clone and the tubes just died. Now I'm considering KT66's just to have fun and play with something a bit different than the 6L6's that normally go in there. I have read about the crazy companies relabelling tubes left, right and center...

So: Sovtek is really Reflector (in Saratov, Russia)
Saratov is really Reflektor
Tung-Sol is really New Sensor is really Reflektor
Svetlana's are now SED
Mullard is really New Sensor (Reflektor?)

Then there's Chinese:
Valve Arts is really Shugnuang
GT is Shunguang

We got Genalex and Golden Lion copies everywhere. The prices are vastly different from what I find online.

All this to say that I'm confused and I don't know what to order! (All of the above except Mullard are making KT66's)

Please help a brother out! Which KT66's can I safely purchase and be floored by? Thanks
