I looked at a nov 69 Audio issue and came up empty.

After much serching I found the details of the passive crossover I used with my 511b, 2x416a IB setup I built many years ago. The design comes from Audio Magazine, November 1969 issue. Using iron core mil spec inductors and a few resistors & capacitors it was fairly inexpensive when built. I had the added bonus of an employee discount from the distributor I worked for at that time.
I have scanned the article in high resolution B&W, but the file size for each page, one of the cover and three of the text are still in the 2.5mb each, range.
Should anyone want to go to their local library & try and find it for their own education, I'd encourage it. Otherwise, if you're an electronics whiz, you might just find it entertaining. My own library
Dialup internet service makes it a lengthly process to send here, although I could try, but it would require 4 full screens to display. I would not object to sending out a few copies my snail mail.

I've been fighting with computer problems for some time trying to put some key features of that article here with poor results, mostly giving up. And it looks like tonight isn't any different. PM me with an email address. I'll send it to you. I assure you, that issue is correct. Article begins on pg 52. " Passive crossover for bi amplifier systems."

Trying to post a link to archive.org read it online
Lots of nice stuff there BTW

Needed to send this other jpg in another panel. Moderator may combine if he chooses.
Very cool stuff gentlemen!!! Thanks for sharing!!!
A not of caution with passive low level crossovers. They do need to "see" close to the correct output load. With the input of most solid state gear being very hi-z, it's often good to connect a 610 Ohm resistor across the output of the filter. 610 ohm and the 50k of the solid state amp works out to around 600, close enough for rock and Roll anyway.

I think you're saying that in the circut I posted,which has 600 ohm resistors, that's close enough.
