Power Supply Delay Finish PCB for DIY Tube Amplifier

Features:

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.

Features:

• Reliable Circuit Design
  
• Carefully selected componnents
  
• Utilizing high quality relays to ensure transparent transmission of power
  
• Finished pcb with components installed. User just need to add their 12V ac power and make their required high voltage connection.
    
• Size: 134mmL/65mmW /27mmH(Height measured from component top to pcb bottom, excluding  components feets)
  
• Come with wiring schematic.
  
• Required power supply of 12Vac 5W or above
  
• Power Transformer are also available in our Mall.
