Elliott Sound Products Project 87A - Dual Balanced Receiver 

The layout for this circuit is virtually identical to the published project design.

The PCB comprises a complete stereo balanced receiver, with presettable gain and high Common Mode Rejection. Requires a power supply (e.g. P05) giving +/-12V to +/-15V at about 15mA.

Project 87B - Dual Balanced Transmitter 

The layout for this circuit is different from the published project design. This circuit has been simplified, but without loss of performance. The ability of the output to appear 'floating' has not been incorporated since that would increase the PCB size and cost, as well as the component cost. In all but the most critical (or noisy) environments this is not necessary.

The PCB comprises a complete stereo balanced transmitter. Requires a power supply (e.g. P05) giving +/-12V to +/-15V at about 15mA.
