Hi everybody,
does anybody have the schematic of the card for the 4355, crossover 290 Hz/ 18dB?
I ask for a friend.
Thanks and regards

Hi Giskard,
i have a new question:
in the manual for the 5235
http://www.jblproservice.com/pdf/Vintage%20JBL-UREI%20Electronics/JBL-5235%20manual.pdf
Jbl wrote that for the 51-5145 card R1 is 5,2 k ohm.
In your post you have a copy where R1 is 6.2 k Ohm.
What is right?
Or i am wrong?
Please help me and my friend.
Best regards
Dieter

Good eye Dieter!
Here you go:
Looks to me like the 5234A manual is right and the 5235 manual is wrong.

Yea, looks like a typo. Besides the curve (thanks, Giskard!), all the 18db/Octave cards have R1, R2, and R3 of same value, both in the 5234A manual (5234A Manual - Link (http://www.jblpro.com/pub/obsolete/5234a.pdf)) and in the 5235, except for that 290 Hz card.
Another typo for the record books. :p

"all the 18db/Octave cards have R1, R2, and R3 of same value"
Yeah, except when you're building the 4430/4435 card which also uses the 18dB/octave card.
