Does anyone have any experience with these? They list them at the tubestore.com, but otherwise I cannot find anything further on them. How do they compare to the other NOS EF86's out there? I have a tight budget & these looked affordable ($27.95) and interesting. Thanks for any help!
Update: I took a chance & got the RFT and quickly realized just how much of a piece of **** the stock Svetlana is! The KT-45 side of my 6545 completely came to life as if I had removed a wet blanket from it! The RFT is quite a bit brighter with lots of low end, punchy mids & very snappy top end. Sort of really brought out the Hiwatt side. I now understand the huge disparity between ANY NOS EF86's compared to the Svet/Sovtek. The RFT from what I could find, was made in W. Germany. I'm not sure of its age, but they are really a great deal if you can find them. I got mine from the tubestore.com for $27.
I was so impressed with the difference this tube made I had to see how much more of a difference I would find in a NOS Mullard. I was able to snag a pristine mesh type Mullard NOS EF86 from the Blackburn factory on Ebay for $22.50! The mullard is quite a bit different from the RFT. I would have to say it brings out more of the Vox side of the amp. A bit darker sounding than the RFT, but with really lush low end and chimey high's. The mids are much smoother than the RFT.
For now I'm leaving in the Mullard, but the RFT definitely has a nice punchy sound. If you still have the Svet/Svtk EF86 in your Z, you really have to try a NOS! I'm now on the lookout for a GEC, Telefunken & maybe a Genelex Gold Lion...So much for saving money!

The RFT looks like it is an older Tesla or grey plate Telefunken style Ef86. I bet its a gooden. Lots of these tubes got re-labeled. Someone will correct me if I'm wrong, but it seems the NOS Ef86's fall into two catagories. The grey plate style and mesh plate style. In my experience, they will sound a little different, but equally nice.
Actually ive seen them in the mesh screen, solid plate screen, and i've got some old rogers and RCA made in eroupe that are more like a little cheese grater looking screen? In fact i think the stock Svets are like that? .... i guess that'd be a tiny piece of cheese!

GuitarZ: Must be great to be a skunk. Eating bird food about 10' from our sun room. I'm clapping and yelling. At best, it might have given me one "yea what?" look while continuing to dine. At one point, there were two skunks and two racoons.

easyed: Guitar Z, I encountered to ultimate garbage raiding combo once. We'd been having problems with the garbage cans being raided by raccoons for weeks. Late in the evening I heard rattling at the cans. I went out and found that he'd allied with a skunk. "OK"

GuitarZ: EasyEd - Someone at work topped us both. The inside of their car had been somewhat ransacked. They were blaming their son. They checked the video. It was a Bear! I'll stick with the racoons, skunks, foxes, and squirrels.

bigboki: In this age and time when everybody are struggling and especially S&Ms I am amazed to see that kind of ignorance. I am really sorry for your experience dear Dr Z but it is for the better. You don't want to do business with those kind of people anyway.

GuitarZ: Didn't want to restart the plumbing thread, so I figured I'd ShoutBox this. How the heck does cleaning the aerator on a faucet cause a leak to start under the faucet? Huh? Arggggh!!!!

The Bad Poodle Experience: well, Mike, it shouldn't have been the cause of a leak. double-check your work.

GuitarZ: I updated in the Plumbing thread that the Moen website says that a faulty aerator can cause a handle/base leak. Eiyy! I really don't understand how plumbing works. I was ready to double check all connections. But, the leaking stopped with cleaned Aerator.
