AMPLI PIONEER SPEC 4 AMPLIFIER STUDER ACCUPHASE MCINTOSH À GAVAUDUN

Ampli Pioneer SPEC 4, double alimentation, superbe état, entièrement recapé/ réglé/ vérifié, condensateurs Nichicon Muse, les 4 gros condensateurs d'alimentation sont des Elko 27000 uf 100V 85° (d'origine avec 4X 22000 uf donc mieux filtrés !). For shipping outside EUROPE, please contact me before buying Description The Spec-4 employs DC construction which excludes capacitors from the NFB circuits and uses a dual transistor differential amplifier with a current mirror circuit in the 1st stage.  This provides a stable operation and also high gain over a wide frequency range.  The pre-driver stage is a class A circuit with a regulated current circuit for the load.  This makes for high gain amplification with superior linearity. Furthermore, there is an overdrive limiter and power limiter circuit which is designed to protect the power transistors and make for added reliability.
