GBOneScreen is GREAT The OneScreen is working great. Perhaps even more impressive is the training support, technical support and sending of replacement hardware after damage I myself caused. Great product. Great team of people.

CNHow to identify the components in the circuit 1. Online power-on test Mainly based on its model or working state to determine the voltage across the pin, such as diodes and rectifier bridges have a tube voltage drop, and the triode should judge the emitter junction voltage or collector voltage according to its working state. 2, offline measurement in the case of power failure, remove the components, measure the unidirectional conduction characteristics of the diode and rectifier bridge, and measure the quality of the triode with the basic amplifier circuit of the triode.
