Product details:
KITS require you to weld yourself.
This kit does not include valves and output transformers.
Adopt imported resistor, Philips high voltage capacitor.
Cathode capacitors are Panasonic with warm sound. Coupled to VIS BC high voltage capacitor, the sound match is very good.
If you want to make it cheaper, you can use 6P3P for EL35 and 12X7 for ECC88. However, the power of 6P3P is lower. In fact, if you want more power, you can use KT88 instead, just adjust the cathode resistance.
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.
Attention:
* Tubes and output transformers are Not Included.
* The tube is a Class A single-ended output,the tube temperature and the cathode resistance temperature are a little high, which is normal phenomenon
