Sino 12AT7 Preamp Vacuum Tube
The Sino 12AT7 / ECC81 is a greatly improved version and is a cost-effective and suitable replacement for any 12AT7 / ECC81.
I got the tube to replace the inverter in a vintage 50's Fender amp. I do have a TON of old legendary tubes that I actually did not like the tones. This one did it JUST RIGHT. It has a medium tone response and is very smooth, not edgy or muddy.
