Title: RCA BC-9A Post by: KA3EKH on February 29, 2016, 09:55:20 AM I picked up an RCA BC-9A mono audio console this last weekend at the Techno Swap fest and wanted to get it back to operational, the console is in great external condition with no holes or modifications to the case, something I am not use to seeing on most but this one is clean. The issue is that someone removed the four microphone cards from the unit and now I have got to clue together at least one microphone preamplifier for this thing to have any sort of use. Figure I can wire together jumper plugs for the other three inputs for line level inputs but want at least one microphone level channel.
Anyone got the schematic or service manual on PDF? Title: Re: RCA BC-9A Post by: W4RFM on March 06, 2016, 09:44:19 PM I am checking, I think I have the book on those pre amps. AMfone - Dedicated to Amplitude Modulation on the Amateur Radio Bands
