Model No: WVT-TPA6N3
This is a tone board with 2pcs tube 6N3 and uses tube 6Z4 as rectification. The low frequency crossover point is 30Hz, its drum rumbling is absolutely shocking from your bass speaker unit. And the high frequency crossover point is 10KHz, which is absolutely delicate. So, please remember that it is not suitable to use it in full-range speaker sound systems.
PCB is first-class PCB quality, that is a double-sided plate with spray tin process, to ensure good performance for large and small current flow. This board is very easy to connect and is ideal for DIY enthusiasts.
The schematic of this board can not be provided. If you need to improve, you can directly replace the related component with the advanced components as same parameters.
Features
1. PCB specification: 205mm*120mm, 1.6mm thicker.
2. Volume/bass/treble/balance adjustment available for this board.
3. Vacuum tubes are placed horizontally to make it easier to find a suitable chassis. Copper pillar height is not higher than 5CM.
4. Vacuum tube: The rectification part of the high-voltage power supply adopts rectification tube 6Z4, which is more musical than the bridge stone rectification. The high-voltage filter capacitor uses PHILIPS BC 150UF*2 and the filter mode is CRC. Filament uses DC power supply through 8V AC bridge rectifier , then using a 7806 three-terminal regulator for the tube filament.
5. The potentiometer adopts high-quality 09 type B100K one. The coupling capacitor uses Hong Kong TE MKP HIFI film capacitor and the resistor is a precision 5-ring metal film copper foot resistor.
Power transformer selection recommendation
1. Power of the power transformer is not less than 50W
2. Secondary voltage of Power transformer:
a) 220V-0-220V/40MA (AC-0-AC on the board;)
b) 8V/1.5A (on the board H1-H2);
c) 6.3V/1A (AC 0-6.3V on the board)
