Options and price standards:
1. Spare parts kit without main capacitor and heat sink
2,Finished board Main capacitor and heat sink are not included
3. Finished board with capacitance and heat dissipation
This board can also be changed to full frequency zoom, just note when placing an order
Schematic address:
Board silk screen D667 needs to install A42, B647 installs A92
Customers need to change the capacitor when they want high voltage, the default is 50V withstand voltage delivery
The green capacitor ERO has been fully upgraded. The German elixir red WIMA has a more delicate sound and no burr.
The withstand voltage of heat dissipation and main filter depends on the voltage of your transformer. Generally, the higher the voltage of the transformer, the greater the output power, the greater the heat dissipation required, and the greater the withstand voltage of the filter capacitor.
Product Highlights:
1 Adopting fully symmetrical dual differential input structure, the input tube adopts Gawain''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s dedicated A42, A92 pair of tubes, and a constant current source with a constant working point. The sound quality is very delicate, the sound field is very good, and the atmosphere is balanced.

3 Under the voltage of DC55X2, the highest output is 300W 4 ohms. Compared with LM3886''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s 68W-4 ohms 40W-8 ohms, the driving force is not on the same level. Note that the 100W of TDA7293 is tested under 4 ohms. 8 ohms does not exceed 60W,Even under AC26, the output can reach 80W 8 ohms.
4 In terms of price, it is even more attractive than LM3886 and TDA7293, and the price/performance ratio is very high.
