Can an Ampeg B25 head handle < 16Ohms?

  1. Is there anyway a 70's B25 can handle a load of < 16 Ohms? Looking at the schematic, there's only a 8 and 16 Ohm tap on the output transformer (I guess the original 2x15" ran @ 16Ohms, with the extension tapping the 8Ohm?).

    Would there be any way to run one with my 4Ohm Ampeg quad?

    Thanks!
     
  2. Not safely. I wouldn't run 4 ohms on my B25-B, that's for sure.
