Transistor Power Amplifier
400W Power Stage 1 Pair K1058 / J162 FET Transistor Refer to Goldmund TELOS 300 Circuit Whole Aluminum Casing
Model No: WHFTA-GVT300
Goldmund TELOS 300 power stage is a typical representative of European style and expensive, which is small dyeing, balanced three-frequency, good extension of high and low frequencies, strong control, sound field restoration real, positioning, accurate phase, delicate, moist, well Listening.
With reference to the circuit structure and sound tuning characteristics of original one, we have made improvements and optimizations in accordance with our process structure design and solved the self-excitation problem of the original one (not by simply adding resistors like some brands). One advantage is that the internal resistance is extremely low, if you add resistance as you liked it will seriously affect the sound quality. Each power amplifier adopts custom-made imported iron core pure copper wire Seiko ring cow, using 3 pairs of Japanese original fever power field effect tube. The circuit layout is optimized, the modular structure design is used, the thick gold-plated circuit board, and the chassis is optimized for heat dissipation structure.
- This unit adopts whole aluminum precision CNC case, and has increased the power indicator of level meter.
- With perfect protection circuit and soft-start control circuit.
- Custom 500W pure copper wire loop transformer.
- Genuine components guarantee the quality of circuit hearing. The filter capacitor is Si Bi 75V82000UFX2, the input field effect tube Toshiba K170BL is precisely paired, and the output K1058 / J162 field effect power transistor X3. Siemens gold axial decoupling capacitor.
- Output power: 400 watts per channel (4 ohm load) / 200 watts per channel (8 ohm load)
