Beware Of Counterfeit Or Inferior LM Copies. LM has been able to purchase and verify these Counterfeits. Also, the 220v models made for the Chinese market are reduced quality and therefore cost. We receive the superior and more expensive models which are not sold in China. We only sell authorized 120v export models with local support and full warranty.
With a power output of 2x30W, it can be used with most of the existing reference speakers. The LM 845 Premium is a combination of two units: One is the amplifier unit and the other is output unit. The LM 845 Premium uses Shuguang 300B tubes in drivers, the 310A for amplifier and Shuguang 12AX7 in pre-amplification.
There are 2 user bias controls for 300B and 845 have been used for bias adjustment and 2 meters has been added to the front plate to allow you to monitor bias with ease. Negative feedback switch is on the front plate that you can choose between 2 levels of NFB to enjoy the different sound outputs. The LM-845 Premium uses 8 transformers (power supply, filtering, coupling and output)!
