The replacement Tweeters arrived safely from California. They play music when connected to the crossover and sound the same best as I can tell, they also measure exactly the same resistance which is great.
The only thing stopping me from building up the one speaker I dismantled is that I am waiting for bitumen panels and binding posts to arrive. The next two thumbnails are for reference purposes, the original x-over schematics and the 66 brochure for the introduction of the face lifted "Woodies"
