Quad 44 Control Pre Amp - $350 firm. 

Upgraded:

 

This is a Quad 44 preamplifier with the following service check & upgrades: 

Includes  the following:

1. Trouble shooting circuit boards replace damaged components with equivalent modern parts. 

2. Make pre amplifier operational and perform update service:

Power supply capacitors and output relay timing capacitor will be replaced with high quality electrolytic capacitors - 

All op amp ICs will be replaced with Burr Brown SoundPlus opa134 audio quality op amp ICs with sockets on main board - 4 ICs

All op amp ICs will be replaced with Burr Brown SoundPlus opa134audio quality op amp ICs with sockets on all modules - 10 ICs 

 I maked it fair as there is a small dent on the back chassis on the bottom. Front top and sides are in excellent condition.

Description

The Quad 44 has five inputs, Disc, Tape 1 and 2, Radio and Auxiliary, which will terminate correctly virtually every applicable programme source available now and in the foreseeable future. 

All five inputs are interchangeable, so that any combination of inputs can be obtained, and options such as moving coil pickup, or microphone inputs can be included. 

The 44 has tone controls, consisting of Filter, Bass and Tilt which enable the listener to correct for those acoustic problems which are amenable to frequency response shaping. 

Used intelligently these controls can improve the results obtained from almost any programme. 

The performance of the amplifier meets the simple Quad criterion, that programme fed through the unit shall suffer no audible degradation, in other words, with the filter switch in the Cancel position there shall be no audible difference between the programme at the input to and output from the unit, when compared at identical levels. 

This is true for all inputs when used with their specified source impedances and within their input signal limits. 

The Quad 44 will sound no better, or worse than the programme fed into it. 

Construction and inherent reliability continue in the Quad tradition and reflect care in both design and workmanship. 

It is extremely unlikely that the unit will become outdated, since any future developments in programme source or circuit technology can readily be accommodated simply by changing input modules.
