Reliable source Psvane CV181-T MKII

Sorry, but I lost all trust of Viva Tubes when they began to gouge their customers the very day the sanctions were declared. They were the 1st to do so and they are among the highest prices of any from the starting day of the sanctions. I won't buy from them if they are available anywhere else which they are IE Amazon & HiFi Part store

Have you called Tube Depot?

strange thing with HiFi Part store is i cant find the the current psvane tube series --art series. IIRC the T mk II is a coupla years outta production. 

i never heard of golden voice tubes-anyone here heard of them, used em, especially the 12A_7 tubes?

Shuguang Electric Company experienced a fire in August 2019 and burned to the ground. They made HAM radio amplifier tubes under an assortment of names like RF Parts, Taylor, Machlett. Their quality was typical Chinesium compared with other countries like Russia for example.

China never issued a permit to rebuild the factory so a group of ex-employees left and started PSVANE. Once again, poor quality and failure rates higher than acceptable.

Russia no longer exports tubes in retaliation for the sanctions so PSVANE has capitalized on this demand.

@r042wal 

Me thinks you are confused.

Yes, factory burned down.

Yes, Psvane was formed by ex employees 

Psvane was formed in 2011, and not as a result of the factory burning down.

Details matter, because you wouldn’t want people to think you were engaging in some kind of smear campaign, and just sloppily throwing info out there.
