Here are listed some subjective views to this matter. Many players wonder if there is any difference if an amp is based on p-to-p or pcb-technology. Point-to-point- or printed circuit (PCB) boards? Power tubes biasing can be done wirelessly either with a normal pc or with a smart phone. This means that there is no need for a separate bias meter. Our ABC biasing system has been developed further to a wlan based application. This option contains ABC system and a ABC meter with detailed biasing instructions. After tube change, ABC inside amp chassis adjusts bias to the targeted level.ĪBC will be an option to all fixed bias Bluetone amps. With these led lights it is fast and easy to find a broken tube and replace it. If led turns off, it means that power tube is possibly broken. When led is burning, it shows that tube is in working condition.

There is also a small led indicator nearby each power tube. With ABC you can also use unmatched power tubes and save money. This check and adjustment is done individually to each tube every time when amp has been turned on. After targeted bias level has been set, system automatically controls it and adjusts it to properly level if needed. This meter menu contains all common power tube types. Bias level is set with a user friendly ABC-meter in a safety voltage level (max. This system adjusts and controls power tube biases automatically. However we wanted to go further and developed even better Bluetone Auto Bias Control biasing system.īluetone ABC is based on a software application with semiconductors. This system has been installed successfully to all latest fixed bias Bluetone tube amps. To avoid that kind of problems, we developed Bluetone Bias Rate bias adjustment system, which makes power tube biasing safe, fast and easy. Inside tube amp chassis there are dangerous voltages. In this case amp chassis has to be opened to to get tubes biased properly. Many tube amps have such a power tube biasing system, that it demands a skilled person to do it. Many people avoid tube amps because power tube biasing is way too complicated. Here we have gathered some information about tube amps and some modern technologies used in Bluetone amps.
