Musical Fidelity A1 integrated Amplifier

ZGAN, paar maanden gebruikt.
25W Pure Class A power @ 8 Ohm Discrete symmetrical topology Planar Audio transistors with 25A maximum output Dynamic class A, slides (NOT switches) smoothly into Class B, allowing more current as needed Therefore drives difficult speakers with no problems Updated transformer to “dual mono split rail” windings Fully independent left and right power supplies Each power amplifier now has double supply capacity Transformer noise and heat dissipation reduced Filtered main supplies Gain block before volume control totally bypassable using “direct” switch High quality and updated ALPS RK series potentiometer Low noise TL071 JFET preamplifier circuitry Discrete current-mode MM/MC phono input stage Low noise current to voltage converter for further amplification and RIAA equalisation Automatic input impedance matching (1K nominal) for MC along with increased gain Original (1985) A1 appearance and circuits with modern improvements Remote control added for volume Modern updated low noise components
