This is a no reserve auction as high bidder wins!!All of our items come from a collection of vintage pro audio / broadcasting equipment from 1950 to 1990 it has all been packed in storage for over 25 years, and whenever possible all equipment has been tested and is working properly. (However)This collection of extremely well made Collins preamp modules from the 1960's is pro audio and takes a certain skill set to set up properly with advanced understanding of circuitry and electrical connections, therefore lacking appropriate cables this falls out of our scope of knowledge and ability to test and is being sold as is. We have made no effort to clean or even dust these units.Please feel free to send us any questions , we will try to answer as best we can. 2) Collins 356B-1 - Program/Microphone Preamplifiers (High Gain, High Output Level) - Essentially a copy of the excellent Langevin AM-5117 program amplifier with ADC instead of Langevin transformers. Unit instructions and schematics at: collinsradio(dot)org/archives/manuals/356B(dot)pdf3) Collins 356A-1 - Microphone Preamplifiers (Medium Gain) - Essentially a copy of the excellent Langevin AM-5116 with ADC instead of Langevin transformers.These vintage tube preamp modules were was used on countless American recordings in the 1950's and 60's.
