The tube chart date code works like this: the first letter indicates the year and the second letter indicates the month.
So if your blackface amp has a date code stamp of OB, it was made in 1965/February.
I'm also not going to get too deeply into technical details of circuitry.
I apologize in advance if I got a date wrong, a model wrong, etc.
I am not an expert on amps, Fender amps, or Silverface Fender amps. I am merely someone that loves old gear, appreciates Silverface amps, loves to write, and loves history.
