Circa '49 Webster-Chicago model 362

[radiotvnut]

Here's a circa '49 Webster-Chicago 3-speed record player that I recently bought from another ARF member. The case is in nice shape and the amp works, even though I'll probably still recap it. The changer plays 33, 45, and 78 rpm records and will need the usual overhaul. The amp uses 3 octal tubes (12SJ7, 50L6, and 35Z5). This player was probably among the first consumer grade 3-speed units. Was there ever an automatic 45 rpm adapter for these changers or will I have to use the yellow snap in adapters?
