6SN7 Tubes

Advice please. I am looking to build Salas phono itch. 6sn7 tubes and 6n2pev tubes. For the 6sn7 tubes there is a blistering choice available starting at $3

to $230

Now I want a good sound but how on earth do you decide which is going to be the most sensible way to spend your money. Are these all going to have broadly similar tech specs or will I need to modify circuit according to which I buy? Anyone know a good uk source?

Love this hobby - black art at it's best.
 
It's all a matter of taste. Most of the older GE's and Sylvanias I've tried in my guitar amps were noisy and microphonic. The best I've had was an old stock Motorola. You can always start with the 3.00 tubes and work your way up from there. They each sound different and "tube tasting" is a favorite pastime for tube enthusiasts.
 
In my opinion, hifi is very different than a guitar amp. With a guitar amp tube choice is more of a personal preference because everyone is looking for a different sound or coloration. With Hifi pretty much the majority will concur on which tubes and parts sound the least colored and reproduce the original sound most naturally when used in a given circuit.
 
I would go with the Siberian $3.00 6SN7s. These have the grid radiator wings, so it makes them 6SN7GTBs, actually. These were "hardened" 6SN7s designed for TV vertical deflection duty, with the enhanced Pd= 5.0W, and which can operate at Vgk > 0V (hence the radiator wings). I've also used Sovtek 6SN7GTBs as well. These proved to not be microphonic.

I wouldn't spend three figures for any small signal type, pure audiophoolery that.

With NOS 6SN7s, microphonics seems to be a common problem with the type.
 
Of course, you could always go with (2) 6J5GT or it's WWII radar evolution, the 7193 (2C22). These are single triodes that are essentially 1/2 of a 6SN7. I use the 7193's in place of 6SN7s in my preamp and the sound is far better to my ears than any 6SN7 I have tried (and I've tried a LOT of them). They are also very cheap - the 7193's I bought were ~$5-7 for NOS 1943 Ken-Rad, National Union and RCA types.

Just another option.
 
I've had excellent results with CV1988 (rare-ish, expensive), 5692 (more common, still expensive), and Electroharmonix (easy to get, moderate price). My own preference is for 5692- they're built like tanks and have the lowest microphonics of any 6SN7 I've tried.
 
I prefer this version:

Version of what? Nice for you that you like it, but this tube is pretty different from whatever 6SN7.
By the way, this forum "speaks" English, so here are the specs of the 6H16 in Russian and English:

Take the 6N1P it has noval socket but almost 1:1 with 6SN7. BTW, it sounds so damn good it is a different galaxy. If you want to sleep in front of your stereo the 6SN7 is ofcourse the better choice😛
 
Not all Soviet tubes are killers, but military ones, especially made for Avionics and Cosmos. Look for a Diamond stamp on them! Some of them like 6S17K, 4P1L, 6N16B, GU-19, GU-50, and similar, were available for military equipment only.

After 15 years experience with ECC82, ECC83, 12BH7, ECC88, 6SN7, 6SL7, 6CG7 etc, I agree totally with Wavebourn! The Soviet tubes are killer!!! All US, Chinese & European tubes sound lame. Thanks for the soviet people producing the best tubes on this planet.
