The shop promises:
The electronic tubes operated by our store are guaranteed to be brand new and high-quality genuine products from the original factory, and we will provide free replacements for any quality problems within one year. All tubes are rigorously tested to match .Buy 2pcs = Precision matched pair. Buy 4pcs = Precision Matched Quad. We have the conditions and advantages to match multiple tubes (four tubes, eight tubes) according to customer needs. The same parameters. It is a professional shockproof and firm package. It is absolutely safe.
Note: It will be shipped after strict inspection again (please do not think it is a fake and shoddy product after receiving the tube).
