Details:
Pcb size:100x59mm (L*W) Suitable for 6Z4/5Z2P/5Z3P/5Z4P/5U4G/5AR4 8 pin tube seat apply for 5Z3P/5Z4P/5U4G/5AR4,connect to 5V 7 pin tube seat apply for 6Z4 ,connect to 6.3V R1: Recommended 47-100Ω, which can reduce the impact on the rectifier tube. R2: The resistance value can be adjusted according to the needs of the circuit, please leave a margin for the power of the two resistances. C1: The volume should not be too large to avoid impact damage to the tube duct, 47uF-100uF is recommended. C2: Try not to exceed 100uF. The above are just our suggestions, you have to choose according to your own understanding and experience.
Package included:
As the picture show Not included tube ,resistance ,capacitance !
