ALTEC 1590B Solid State Power amplifier Pair (Worldwide Shipping)

  
[Description] You are looking at a rare ALTEC Model 1590B solid state Amplifier. The 1590B Power Amplifier is an improved version of 1590A Power Amplifier, designed for applications where uninterrupted operation is required. Capable of operation from a 120 or 240 volt ac source or a negative grounded 28 vo lt de source, the ALTEC 1590 B is immune to power failure. Incorporated in the amplifier is a'Fail Safe', silent, automatic transfer to de operation in the event of power failure. When ac power is restored, the ampIifier will automaticaIly transfer back to the ac source and provide a float charge to the debattery, returning the battery to a fully charged state.

Frequency response of th e ALTEC 1590B Power Amplifier is ±l. 0 dB 20 to 20,000 Hz. The ALTEC 1590B Power Amplifier also contains a highpass filter for use in speech systems, a high input impedance of 15000 ohms, with an octal socket provided for plug-in transformer to input line isolation. Featured with the ALTEC 1590B Power Amplifier is the exclusive dissipation-sensing circuit, providing protection to the output transistors.

If a malfunction occurs, or if the load represents a severe downward mismatch in the presence of high-level program material, the sensing circuit prevents the output transistors from operating in a mode which would cause damage or degradation. Because the action to the circuit is immediate and effective a tall frequencies within the passband of the amplifier, only that portion of the program material which would cause damage to the transistors is limited. The amplifier recovers its normal function as soon as the output fault is removed.

The ALTEC 1590B Power Amplifier, designed for rack mounted use, occupies only 6 units of rack space, and allows easy access to components via the hinged front panel. All circuitry is accessib le for servicing when the front panel is open without removing the amplifier from the rack. A printed circuit board(PCB), plugged into a receptacle contains all active input and driver circuitry. Output transistors and associated drivers are mounted on a massive heat sink assembly which unplugs from the rear of the chass is when the protective shroud is removed. As you can see in the video clip, this item is in great condition. [Specification] ALTEC1590B: Serial Number: 5595(391140)/9799(391431) Gain: 67 dB Power Output: 200 Watts.
