Parasound HCA-3500

Two Channel High Current Amplifier

Dont judge a book by it's a cover! This Award Winning High Current Amp has seen lots of wear on the cabinet, but still sounds amazing! Original box and packing are not included. Owner's Manual is easily found on line.

FEATURES:

Independent power supplies for each channel for true dual-monaural operation

Massive encapsulated 1.4 kVA toroid power transformer for each channel

97,600 uF power supply capacitance for each channel

Multiple polystyrene film bypass capacitors in power supply

Direct coupled design uses no inductors or capacitors in the signal path

DC servo direct-coupled audio circuits with 0.5 Hz rolloff

Output transistors direct-coupled to speakers without LRC networks

Cascode Class A input stages with matched J-FET pairs

Hand-picked complementary MOSFET transistors in high voltage driver stage

High-bias Class A/AB operation provides 15 Watts of pure Class A operation

8 complementary pairs of 15 ampere 60 MHz output transistors per channel

High-quality Neutrik XLR jacks for balanced inputs

Two sets of gold-plated metal structure RCA input jacks for balanced operation

Two sets of gold-plated 5-way binding posts facilitates bi-wiring

Multiple protection circuits, temperature sensors and silver-cadmium relay protection

Glass epoxy circuit boards, double-sided for precision

Two hand-made audiophile-grade AC power cords-separate for each channel
