Power Supply Delay Finish PCB: Specially designed for DIY Tube Power Amplifier
Reliable and circuit design for protection of tubes in tube amplifier made them ideal for DIY Tube Amplifier.
If insufficient time is allowed for proper warming up before application of Anode Voltage (High Voltage), vacuum tubes would decrease life span significantly due to the effect so call "tube poisoning"
To ensure the performance of your tube amplifier, no matter pre or power amplifier, to protect your expansive or vintage tube and to maintain it service life, it is always benefitial to ensure tube heater supply voltage applied well before the anode voltage.
This high voltage supply delay feature can be found in many famous high-end tube amplifier.
This product is only for DIYER with sufficient knowledge in electricity and know how to avoide danger from electic shock.
