RCA BA-43/BA-45/BA-46 Amplifier/Compressor/Limiter Units in BR-23 Rack

Complete RCA Amplifiers, Compressor & Limiter Rack. This package consists of the following components:

* BA-43 Program Amplifier

* BA-43B Program Amplifier

* BA-45 AGC Compressor/Expander Unit

* BA-46 Limiter

* BR-23 Rack

* all manuals pictured, including the rare master manual for the package!

* units comes double-boxed for protection as it's very heavy.

Some history: We purchased the rack-mount frame NOS, so its in great shape. The other units were purchased one at a time. Some work has been completed by our tech as follows:

* Recapped all electrolytic caps in all modules. 

* BA-45 compressor/expander passes audio, but does not function.  Further component/block testing will be needed along with calibration of unit to function properly.

* BA-46 limiter is not functioning as well.  Substitute transistors appear to have been replaced years ago.  I suspect one or more of those contributing to the problem.  I did not investigate further.  I recommend tracking down actual parts and replacing all in both limiter units before calibration.

* Please note that limiter modules must be inserted in the rack in order for the preamp to pass signal.  Connectors are wired to have limiters inserted.

* Side 1 (Left) of the rack module is wired correctly for A/C and audio I/O and the only slots useable to test modules at this point.

* Side 2 (right) needs to be rewired and configured to mirror side 1.  I replaced one bad connector, and wired the connector side of the audio output.  No further wiring changes have been made yet.

We are selling this package as-is with the buyer knowing here that further work and testing will be required to get all of the units working both individually and as a package wired correctly within the frame.

We have way too many compress/limiters and other equipment and do not have the space anymore, nor the time to purse this project further, so we are reluctantly selling this package as-is.

Please email with any questions. See our other listings for more studio equipment. 

Thanks!
