Kit hybrid tube-MOSFET stereo headphone amplifier design by Rogers Gomez (Roggom).
Kit termasuk PCB fibre glass FR4 dan semua komponen on-board (yang terpasang di PCB) kecuali tabung 12AU7. Komponen hi-grade.
Anda solder sendiri (do it your self, DIY) biar asyik.
Circuit design:
-Hybrid tube/MosFET (12AU7 tube and IRF510 MosFET).
-Single-ended class A.
-Apply CCS (constant current source) with LM317 regulator.
-Low voltage: 12-13.8 volt DC.
-Simple, small and compact, good sound quality.
Komponen-komponen hi-grade:
8x resistor Vishay Dale dan Takman (tergantung stok).
2x precision trimpot multiturn.
4x elco Elna, Panasonic FC, Vishay BC, original Rubycon (tergantung stok).
2x capacitor Siemens Epcos MKT, Elna Silmic II/Cerafine, Nichicon Muse ES (tergantung stok).
2x MOSFET IRF510/610.
2x IC LM317.
1x soket tabung 9-pin PCB-mount.
4x heatsink TO-220 (PCB-mount),
4 set isolator, mur-baut-ring.
1x PCB 10.2x5 cm (fiber glass FR4 with green solder masking, silver-plated, overlay).
Total 30pcs.
