Anyone try the new Psvane Horizon tubes?

[Dr Morbius]

I just bought a quad of Psvane Horizon EL34 tubes ( I’m normally very leery of Chinese tubes, among other things ) but Amazon had them for $75 a pair. Not bad price wise! After running just over 20 hours one tube went bluey and a loud pop, was afraid of damaging my HH Scott 272 amp. Stuck a backup pair of Tung-Sol’s in and no harm was done. Amazon said we’ll send you a new pair now so send the bad pair back within the month. 2 days later got the new pair and installed them and 5 hours later running nice. This worked out so well I ordered another pair for backup. Sounding real nice so far!
