Be extra careful - Quality Issues
I bought a matched quartett to replace the same power tubes in my amp.
Replaced and biased by a pro tech, within 2 months, the amp started crackling sounds due to a faulty power tube, generating sparks.
This wasn't bad luck as I had a similar issue with the EL34s of the same brand, which i had to return as well due to a wrong match 27 to 48 :(
