“Specializing in vintage vacuum tubes from the 1920s through the 1970s, most are priced from $10 to $30, including shipping. This includes many that typically sell for much higher prices. I have a fairly large stock and because I bought them at good prices, I can sell them for such low prices. Remember, Bushda says all tubes are guaranteed to perform as expected or will be refunded with our no-questions-asked return policy.”
