I bought these valve from ebay, seller is American.
Can anyone tell me these one are fake or real one? What is different between Tesla and Teslovak name?
Tks
looks like some chinese tubes I have, there is probably nothing wrong with them. But I would feel tricked if they said it was Tesla.
The new 'tung-sol' kt are indeed produced in Russia and not an english made tube.
To be honest I don't see the point of getting NOS power tubes.
