Product Features

1. 300B and 845 tubes are ideal combination. This amp is suitable for different loudspeaker box as long as its Response Rate is greater than 85DB. For vocals and strings, you'd better to choose bookshelf type speaker. If you like symphony, floor type sound box is a good one.

2.There are 2 current meters on two sides of the amp(as the silver model picture shows), which can professionally supervise the working of the machine to ideal status. On the one hand, it can adjust the balance of left and right sound track. On the other hand, it can adjust anode current when you upgrade the tubes and make the machine and new tubes work perfectly.
