how to I.D. drivers...

[bernieclub]

I just came across a pair of model 19s, and I can't identify the compression driver. The woofer is clearly labeled 416-8b, and the horn is the 811-b, but the driver only has some long strings of numbers that look like inspection or serial numbers. Any way to I.D.?
Thanks!

Shine a flashlight down the horn throat, if you can see an orange plastic phase plug the drivers are correct.

If the driver has a dimensionally equal "square" or cylinder shape, it's an alnico 802-8G.

If the driver is thin and looks like a 5/8 inch thick slab of ceramic between 2 steel plates, it's a 902'8A or B, and would indicate later models, but since you've already indicated alnico woofers the horn drivers are probably alnico 802's as well.

Just my .02 y'all understand............

The rear cover on the 802-8G should have 033952 stenciled on it or a label saying 802-8G.

As bowtie said, look in to the driver past the screen if it is still there. You should see an orange phase plug with lines radiating from the center to the outer edge.
