Description

Linlai™ Global D Series (aka Dream Series) is the newest addition to the Linlai™ tube lines in 2022.

The D series tubes have tube internal plates coated with Purified Titanium to absorb escaped gas elements during tube operation. Such a design allows better reliability & longevity plus lower noise level of the tubes, and provide a ‘blacker’ sonic background.

After extensive testing in the Chinese domestic market and passed Grant Fidelity’s tight QC screening criteria, we are finally ready to bring them to the western market audiophiles！

Linlai™ Global D series (Dream Series) 7300B-D (aka 300B-D):

Linlai factory opted to use the 7300B model number, rather than the commonly known 300B model number. This tube is 100% interchangeable with a standard 300B tube. It provides a slightly higher plate dissipation rating than a typical 300B and offer a higher output than a typical 300B, but it doesn’t require any circuit modification to suite.

To make it easier for western customers to search for this tube as 300B substitutes, we have opted to still use the commonly known 300B model number in our marketing and labelling.

This tube has an ‘egg shaped’ glass enclosure. See below dimensions (in mm, to convert to inch, divide the number by 25.4) for reference:
