I have a mid sixties vintage Ampeg portaflex. (fliptop). It's the B18N. The amp makes great vintage sound, its 50wrms I believe. However I would like to run something much more contemporary in terms of speakers: say a phil jones bass 4 or 6 speaker cabinet, or perhaps something from EA or Bergantino. any suggestions? I play fretless and I want to try some ultraclean speakers with the old ampeg tube head. Besides, the 18 bottom weighs about 75 lbs. I think my back would love something about 1/2 to 2/3 that!
