Groove Tubes Amplifer Tube Bias Tool
An inline socket adaptor tool that is placed between the output socket and the output tube which allows the setting and measurement of bias using the current draw method.
The bias allows the bias checking, setting, and adjustment to be done in the field or anywhere with a minimum of tools. All that is needed is a simple meter and a screwdriver. The settings are able to be duplicated at a later date, such as when changing tubes. This is not possible with the scope and signal generator method. This is the perfect tool for the band on the go as it also fits in any toolbox.
The average cost for a bias adjustment can be $50.00, so the Tube Bias Kit can pay for itself very rapidly.
The photo shows the meter, which is not included in the basic bias tool cost. The meter is available as an item or in a kit which includes the bias tool, manual, and meter.
The bias tool comes with a full manual.
