Folks,been a while since I posted lots of looking around though.
I was lucky to pick up a pair of model 19 in very nice shape with walnut veneer.I listened to them before taking them home and was amazed.
Curious to check all the drivers.One set has the 416-8z lf driver and the other set has the 416-8b driver.The frame/cone and phase plug look the same on both but the magnets are differant.I measured both @ 6.7 ohms.
Both sets have 811-b horns and the drivers look like replacements with the code 27-03-033952.driver.with a small stamp (a3)Both hf drivers measure 6.7ohms as well.
The foam has rotted and missing for the horns.I also have a spare 811-b horn with a 902-16a 160hm driver that measures 8.2ohms?.
While listening I coudn't tell the differance between the two woofers,are they the same specs with diff magnets?,they are both alnico.
Are the hf drivers generic replacments?
Thanks for any help,
Rob.
