Here’s a matched pair of Teac Concertone 507 tube preamplifiers. These were owned by Mama Cass and used on some of her recordings! These are ultra rare preliminary versions of the model with superb sounding even rarer Tam radio Tamura TR-405 output transformers. These preamps sound phenomenal, like a pair of Ampex 351’s clear huge tube sound. They could benefit from a recap at some point but work well and can be used as is.
