Title: Looking for clear original Vox AC50/2 schematic OS/053??
Post by: Jalmeida on April 29, 2023, 01:20:42 pm
Hello folks,

I scored a 1964 AC50/2 rare smallbox that needs some attention. I am having an a hard time finding the original Vox OS/053 schematic that is readable. Checked the schematics here but just a redrawn one with some details missing. Anyone have a clear original drawing they can help with? Here’s a picture for anyone interested.

I have been all over that page since I ordered the amp. That second original scan of the schematic with the typed clear values is exactly what I needed. No clue how I missed that. Thanks alot!

That schematic was splitted in two parts, the Preamp and the Power section, I joined the two parts in a whole version of the schematic, may be that Is the reason you didn't noticed It
