Unfortunately these tubes are not even close to what I had in mind. Why? Well... I know most tubes are made in Eastern Europe, ok... but if a Russian brand obviously buys the copyrights to use other brands names like Mullard... the I really want a tube similar as possible for the much higher price tag. No, this didn't happen. These tubes came with the Russian pins ! (these are thinner than the original ones as most of us know). I measures them and unfortunately they are not very strong too. I compared with some used ones from the 80th and those measured really much better.
I really don't understand... why does a tube factory pretend to fabricate Mullard tubes using the Russian pins. We are no idiots ! ! !
These pins will cause trouble long term. And there's absolute nothing Mullard-ish inside :-) sorry folks, this could have done better.
They are not damaged and they work, so I can't return them.

I put two of these in a 68 Band Master, replacing 2 Groove Tube 12AX7's. Made a good sounding amp sound really great. Tone was night and day. Really tightened up the sound a lot, with a Plexi type break up and natural compression, yet still very American sounding. Worth every penny.

Very good product

Nice tube, low noise and balanced sound without harshness.

In my opinion its the best 12ax7 on the market-pricey but worth it. Zero microphonic noise ,very smooth solid drive qualities.

As always! These guys have anything and everything I need and more! And... At an unbeatable price!
