The inner circuit has adopted the famous Matisse circuit, with some modifications basing on that. There is one exported ECC81 and one ECC83 for each channel, and both of the tubes for each channel have been handpicked with strict match, in order to ensure the coherence and improve the stability.
There is also proper passive feedback net to improve the frequency bandwidth and kinds of distortions. It especially insists on the importance of material and match, therefore, it adopts E-transformer which with lower noise and magnetic leak, to get more reliability and stability. There is also CLC filter net matched the tube commutation to join in the power supply system. Both of the remote control and hand operation models are available.
