Jim of LiL Dawg amps is currently building me a 18 watt 5F10 Harvard style amp using a Princeton chassis and a 12 inch cab. I am mostly looking for it to stay true to the original sound of the amp but I am flexible as long as the speaker is American voiced. I'm a bit torn between using a higher and lower efficiency speaker and I'm partial to the Alnico "chime". I mostly play clean and may sometimes use a pedal for some overdrive. I included the speakers in this survey, based in my research, that I think would be best for this build and would appreciate everyone's opinion. Please let me know if there are other speakers that I should also consider.
