diy tube amp kit

The original goal of this project was to have a compact octal tube OTL headphone amplifier that would drive low impedance headphones (down to 32 Ohm). I also wanted an external choke. All those needs forced a custom PCB.

If you've never experienced the genius of the 5e3 circuitry, you owe it to yourself to build one. It is no wonder that the Tweed Deluxe 5e3 remains the first choice of top musicians. Deluxe Tweed 5E3 Kit.

6sn7 + 300b single-ended output form design This is DIY KIT,you need to solder it by yourself, If you want the assembled board,pay more 12USD,PLS mail me! NOTE: 1.This package does not contain the required five tubes and transformers. 2.Output transformer must be connected to the speaker to boot, If not the board will be burned. 3.Input voltage to the terminal connection must be strictly in accordance with the circuit diagram.the other parameters pls according to the PCB 4.Do not touch the hot tube. 5.The board must be test well before install the tubes ,if not the tubes easy be burned!.

Power amplifier level 6P3P standard connection, 6P3P for the entry-level products. This connection is characterized by: high amplification efficiency. To achieve the characteristics of the power amplifier tube table provided by the output power.

Parameters: PCB size: 170x99mm Transformer voltage: 230VX1 (can range from 200V to 250V, greater than or equal to 300MA) 6.3VX1 (2A current) Output power: Class A 10Wx2 (You can choose other tubes according to your request, Small power: 6P3P*2+12X7, Or for large power you can choose KT88,remember to adjust the cathode resistor) Some customers have reported that the resistance is not big enough. There is no need to worry about it. All the precision calculations, such as EL34 cathode resistance current is 50MA, the power consumption is only 0,85W on 330 ohms. We are equipped with 3W imported resistance. Absolute capacity is abundant.
