Goplus 7FT Artificial Christmas Tree Pre-Lit Optical Fiber Tree 8 Flash Modes W/ UL Certified Warm White LED Lights & Metal Stand

...but also add the anti-crush capacity to the tree..
8 Flash Modes - Goplus Pre-lit christmas tree has 8 different colorful flash modes, like combination, waves, sequential, flash and so one. You may choose appropriate mode with an adjusting button and the light color of optical fiber will change as well..
Pre-lit with Electrodeless LED Lights - This christmas tree is pre-lit with optical fiber tubes and low voltage electrodeless LED lights with 7 different colors, these electrodeless LED lights are energy-efficient and long lasting. All the lights of optical fiber will keep lighting only with the open of light source, even without the LED light. Pre-lit design saves your time to set up electric lines, you just need to put your favourite decorations on the tree..
Metal Stand - Goplus christmas tree uses metal stand instead of cheap plastic stand, and add plastic cover on the end of the stand. Through this design all we want to achieve is to add the stability of the tree and protect your floor..
Easy Setup - To finish the assembly of this tree it requires only few steps, after putting branches and metal stand together, all the tree requires you to do is straighten out the branches, so the tree will achieve the best effect..

Connect the 6J1 tube pre-amp between sound source and amplifier, it will effectively filter digital flavor, the music and human voice will be relatively good.
Eight 470UF capacitor filter is very clean, excellent power system to no hum, filaments are powered with DC 12V and need to be connected in series in order to reduce noise.
Coupling capacitor is electrodeless electrolytic capacitor with high frequency and low resistance.
Using DC 5.5*2.1 socket and AC 12V transformer, you can also use AC 12V transformer without plug, just need to weld the power cord onto the circuit board.
This kit comes in parts so you can assemble them together by yourself, enjoy the process of building your own tube amplifier.
