suggestions?
going into some Watkins repros (Jokers)
“Goodmans Audiom 51” is waaaaaay to wide a field to be able to answer this!
Over the decades these speakers were produces, they were made with MANY variations! Some had cast frames, some did not … some had smooth cones, some had ribs … some used AlNiCo, some were ferrite … some were true 15-watt max speakers, latter they were 30-watt.
Sooo … narrow it down and maybe I can help!
