They are 3 separate things. The big chassis with transformers and chokes and the two pre’s I purchased a long time ago from an AWA collector. They used them (along with other modules) in Sydneys AWA broadcast room. I’ve started stripping them down today to clean the chassis and respray, followed by a electrical restoration. They are more show pieces part of Australian broadcast history and missing parts for it to be working again. I plan to auction them off later next year. The Stromberg Carlson unit came out of a 40’s radiogram console I found next to my train station. I disassembled the speakers, Garrard turntable and the radio/amplifier unit for restoration (completed now sans the 74rpm Garrard table) and my mate took/completed the restoration on the wooden console. They’ll be listed online for sale after the new years.
