Digital bias current measuring device for vacuum tube guitar amplifier (audio amplifier) BIAS CHECKER TEC-BC1
Texol Co., Ltd.
About This Product
The bias checker can easily measure the current flowing through the tubes installed in the amplifier, making bias adjustment easier. Because it is compact, it can be used at concert venues, recording studios, and at home.
Vacuum tube amplifiers produce completely different sounds depending on the bias current settings. In addition, the bias point changes with use, so by regularly adjusting it with this device, you can maintain stable sound quality.
If the heater is an indirectly heated vacuum tube, the bias current can be adjusted for both AC and DC ignition. The amplifier that can be used is to have heater voltage (e.g. 6.3V) between pins 2 and 7. Two socket adapters are included, allowing you to adjust two bias currents almost simultaneously. However, when using two, please use the A connector.
■Features
