*We take famous Matisse Fantasy Line Stage circuit as reference to design this Tube Pre-amp, and modify much ourselves:
 
1. Re-design PCB circuit,try best to shorten lenght of signal wire, strictly use single point ground connection to get  left and right channels more symmetrically, and higher S/N ratio (94dB)
2. Adopt DALE reistors and 4pcs ERSE audio grade capacitors(99.99% high purity OFC lead) for signal part;
*use Germany WIMA capacitors as Decoupling capacitor
*use 2pcs NIPPON CHMI-CON 450V, 220uf electrolytic capacitors in power filtering circuit
*use TOCOS 100K step potentionmeter
*use high quality golden plated 9pin ceramic tube socket
*use 2pcs Jan. 5670 tubes inside the chassis

3. Adopt customerized pure copper wire EI power transformer, high power rate, low temeperature
4. Adopt Aluminum chassis with Drawing oxidation surface treatment. 6mm thickness front gear plate,
5. switchable power switch for selecting 110V/220V
