JBL stocks and sells some parts but I don't know if they have this part in stock. The email for the parts dept is parts@harman.com. If the full model number on the amp is GTO14001, the service manual gives 1001-3002-10 as the part number for the inductors.
If they are defective, it may be possible to rewind them. Post a photo of the damaged inductor.

Iv put in back in and solderd it now. But it must be that seen as iv rewond it and now it makes a faster arcing sound and will give a higher output level.
There was no burns or marking. But the wire has a cotten look coat to it and one part i could see the wire exposed ? Iv orderd a inductor meter so i can check things in future and msy also help rebuilding this one if i carnt buy one.
Thanks fir the emsill address il give them a email now.
Any idea where to get the wire used for them?
Kind regards

Magnet wire is available from many sources. If you order, you must get the exact wire size. This requires accurate measurement of the diameter. Magnet wire is made in 1/2 gauge increments. Dial calipers are typically needed to get an accurate measurement.
does it not say in the service manual parts list
DIP 30UH/40A ETD49 ф0.1*80*6 13TS
I don't understand what its saying, do you?

Some of it but without seeing the wire or the inductor as a whole it's difficult to say.
ETD49 is a core but it doesn't tell you what the material is. It seems to say that the diameter is 0.1 but doesn't give the units. 13ts=13 turns?
Post a photo of the inductor.

its working fine now and maxing out my powersupply 120amps
clean on the scope as well 49vac 2ohms
but I know its faulty and needs fixing
I hope I can get a replacement part or rewind this one
uploading photos now

one on the right ( suspected ) faulty
thought id upload a picture of my power supply I put together 🙂
drawing 120.03amps with touchscreen temp control

If the output transistors are driving the same waveform into both inductors, and the cooler one is not defective, the hotter one could have either a defective core or a shorted turn somewhere in the windings.
How cani i check output transistors waveform? Put scope on drain legs of transistors?
Kind regards
Kind regards
For that amp, only half of the output transistors will have the rail-rail square wave on the drain but that's a good point if there's no risk of shorting to anything nearby.
What's the make/model of that 120 amp power supply?

I have brought new ones that are ibm and put out 236amps each.
hoping to put them together and increase the voltage to near 14.4 volts but it has a protection circuit.
good cheap supplys.

If you need an inductor for that amp I have one out of jbl 1400.1
Same thing was wrong with the one I had in the bench and the owner decided he didn't want it fixed so I put the board in the scrap pile
So if you need a replacement one I have one I can grab off the board for you
Pm me if interested

S Merlington I have pm'ed you..
really in need of that part as nobody stocks it from what I can find out.
kind regards
