That cabinet is likely a Tremolux cabinet,

Winnie Thomas,

You would have to look inside at the wiring to determine which circuit is correct. I’ve never heard of AA185, or 10″ speakers in a Bassman. All piggy-back Bassmans had two 12″ speakers, until the big cabinets with 15s became available in the Silver Face era. Either your information is skewed, or the unit has been modified. Don’t pay too much for it.

Brian Arnold,

I am thinking of buying what is being called a 1966 Bassman head and cab, and I’m confused about several things. First it has a AA185 tube label so shouldn’t that make it a 1965? And secondly, it has 2 10″ Upton speakers which the owner believes are the origin as they are stamped 39th week of 1965. Again – a ’65 or a ’66? And I thought they only made the cabs with 1×12’s during that time… Thanks very much for your help.

Mike Tarbox,
