Mullard EL34 or EL84 made in Russian

Thanks for your response. I checked the website and the price for Mullard made in England cost more than $600 for quad. Russian made Svet El34 about $90. I brought EL34 Svet local and hooked up with Dynaco ST70. Sound like solid state with tight bass and mid range not softer like EL84. I also have one question on NOS tube as I read on website, still do not clear to understand the sound NOS tube comparing without NOS tube.
I do know why people love tube sound comparing solid state. Eico HF81 makes Wilson 3.2 singing much better with more bass tighter and midrange softer and warm. I used to hookup 3.2 with Mark Levinson 23/26 or 335/26. Less bass and sound is more midrange. I must sell 3.2 but after hookup 3.2 with Eico HF81. I deeply love 3.2 as base tight and midrange softer comparing Klipshorn.

AS you listen to a tube amp more and more,you will start to notice the vocals,brass,cymbals,etc. start sounding more realistic.It may take a couple months or more.Then try a solid state again,it will most likely sound thin,or like something is missing.Tubes aren't for everybody.A lot of times on amps you may not notice when you upgrade,but you will notice a system that is not as good as yours real easily.If you listen everyday,the time will be shorter.♫

Every brand of new tubes sound different.The same goes for NOS tubes.Most new tubes just don't sound as good as the old tubes.The good news is,the new tubes are starting to get better.The old tubes were made for years,and perfected.Then transistors came along.The new tube makers just don't seem to have it down yet.They may have made tubes for years,but not audio tubes.The Russian tubes were made mostly for the military,not audio.But they are working on improving their audio tubes.The old tubes keep getting more expensive because the world is running out of them.

Russian Mullard El34 tubes sound is good with tight bass and soft mid range. I have a change to test with England Mullard EL34 borrowed from my friends ($450 for quad 1972). Sound is increable with softer midrange and a little to bright for classical or vocal. From 1 to 10, Russian is 7 to 7.5 to comparing to England 10
