JBL's site has 3143 and 3145 schematics, but no 3144.
Anyone know where that might be available?
It looks like 3144 was used with 2235H/2221H/2425J/2405 in the 4344

Hello,
The 3144 is the same as the 3145 and it was used in the 4344.
2235H/2122H/2425J-2307-2308/2405.
Thanks Giskard. I'd also picked up on your answer to this on another thread a while back.
Fixin to build two of these. The center-tapped inductors are in JBL's parts book and I ordered them, but haven't seen the goods yet.

Cool! :)
Did you order them from the Pro Parts website or did you talk to a person?

Giskard,
From the web site. The part numbers appear to be
61020-01R0 for 1.0mh
61018-0R16 for .16mh
... gleaned from the 3155 schematic which has a more complete parts list.
John
Yeah those parts are for the 3155.
The 3144 and 3145 parts are 41090 for the tapped 1.0 mH and 50344 for the tapped 0.16 mH.
I really can't remember which were set to what, but I'm thinking one set was set to -6 dB and the other set was set to either -3 dB or -4 dB.
Anyway, I'm sure it will all work out.
Thanks for those numbers. It looks like JBL messed up the order, so I have a chance to get the proper inductors if they have them.
FWIW, the 3155 schematic is labeled -4db
so the 3144 must be -6
"Thanks for those numbers."
You're welcome.
"FWIW, the 3155 schematic is labeled -4db so the 3144 must be -6"
That would be it then. I just couldn't remember off-hand and didn't think about it too hard :)

i would like to know the dcr of this .16mh coil.

If you can't obtain them I have used the alternative of split air core inductors successfully
