An early "Vox Sound Limited" AC50 made by Dallas Arbiter, early 1975
Box and cover
The main page on the "Vox Sound Limited" AC50s made by Dallas Musical Limited and CBS-Arbiter from 1975 to 1976 is here.
Things to note. The cover is slightly different from earlier AC50 covers, the material having a more pronounced texture, and the interior being smooth black. Corner protectors are plain (ie. they do not have "VOX" imprinted on them). The nuts for the screws that secure the amp to the slider board screws are no longer cage nuts (captive nuts) but are bonded to the chassis.
The warranty card and literature that came with the amp are here.
Pictures of the upper chassis and preamp are on this page. Details of the underchassis power section to follow.
