Yes, see the seeburg hf-100g hifi with a little metal 5 inch tweeter...and a .5 mf as
crossover. The amp is slightly different as well..it is the last to use field coil main speaker.
The issue is really the beautiful little red head cart that looks so cool..or if you are still using the original issued black head...either of these is your limiting factor...the overpriced pickering replavcement is nice...the "thorpe grey" aftermarket carts on ebay are good..The red head or black head are ok for pre 1959 or so discs after that some good , more bad..
I tried to add just a tweeter to a seeburg, and though process of elimination , discovered the amp was capable of the sound I wanted but it needed a better source, namely stylus size, pick sensitivity and riaa curve for better brighter sound that the new vinyl discs are capable....here is a sample (my father in law's band) on my G with thorpe cart.Listen to highs stock system newer carthttp://www.youtube.com/watch?v=405_8JxPT80
