Can’t buy output tubes anywhere except from manufacturers at high prices.

Especially KT types and 6550s. Their prices if you can find them have skyrocketed. 

I was referring to Kt types and EL34. 

I took a look at VIVA tubes and it seems they are fully stocked. I guess I have been looking for tube in all the wrong places! 😂 

I wonder how much sales have been affected by the tube shortage for audio manufacturers that specialize in tube equipment?
