For quite awhile, I've been hunting for an NOS or new-production 300B tubes for my Trodt 300B amp. There are a lot of choices out there, both very pricey and reasonably-priced ones. But I ended up with these mid-price PSVANE300Bs which has given me a nightlong break-in period of listening pleasure.
Thanks to Noel Deslate/Audio Amplified, the authorized distributor, for making PSVANE tubes available here in the
Philippines.
