EZ4 on the Me262 B1 ???

Default EZ4 on the Me262 B1 ???

Hello,

Looking at pictures of the funk installation in the Classic book serie on the Me262 B1 located in the South Africa military museum.
In the fuselage rear, there are supports for the fug25 (AR25), fug16 (ARZ16), fug125 (EBL3F, VR3).
Strange is I do not see the marking for the Zug125 (F399), but a frame for the U11 (marked F387) and what looks like a VD3 surrounded by five supports in the typical pattern of the EZ4 frame (marked F3xx, last two numbers hidden). The VD3 has the cover removed, so you clearly see the connector plate for the 4 and 22 pins band cables.

What would a EZ4 do in this plane ??? Substitute for a not yet available ZuG125 ??

Thanks for any insight.

Don't know if I can put a scan of the book's picture without infringing patents/author's rights.

hello, are you sure (F387) is the frame of the U11? I think, that this place is under SG120, the system Fug 120?

Hello,
I do not have a manual for the Fug120 with F numbers, nor pictures of Fug120 frames.
That frame looks like the U11a frame, but of course would make more sense to have a mix of Fug125 and Fug120 devices.
Would you have additional doc/manual/pictures on the Fug120 (besides the well known one on nonstopsystems) ?
Cheers

I still have not found any detailed documentation about the FuG125 Hermine, I have components and Fl numbers, but no pictures to compare. The U11 was used with the PeilG 6, so did not have anything to do with either the Hermine or the EZ4. The U11 has an extra Ward-Leonard winding to drive antenna motor which is not required. I have seen the U10 used for powering the Ebl-3 receiver, so perhaps it is a standard U10E frame. The Me 262 b1 had a FuG 125 C with an additional intercom amplifier EiV 125, so my guess is that the EZ4 frame was used for the intercom amp. Perhaps the components of the V3 and Zug 125 were integrated into the EiV125 amplifier.

Any chance of posting the pictures?

regards,

Funksammler

Unfortunately, I do not have FuG120 F-numbers, but if you look at the system components (or what's left of them were), it is first FuG FuG 120, next FuG 25, and finally FuG 125 (with EBL3F F357, F367). Please Funksammler confirm the F number. Unfortunately, the greatest mystery to me is what's on the wall of the fuel tank and the arrangement Psch 120 in cockpit???

Hello,

Here is the picture: you see the frame F387, a place for a F388, the F204 (WK25), the F389 (VR3) and on top the F3xx (hidden by the HF plug). The AR25 and ARZ16 in the background, as well as the EBL3F frame.
According to the Fug125 manual, F389 is the VR3 and F399 the Zug125. There is no mention of the F387 and 388.

Regarding the firewall (not on the picture), all the frames are part of the Fug128 Neptun installation (F29x numbers).

Very interesting. If you look at the connection box of the "EZ4", you notice a shielded cable entering where normally the antenna cable would enter. Shielded cables are typically used for audio cables, supporting the notion that this is for the EiV 125 intercom amplifier. The Umformer frame is probalby could be both U10 and U11, they are actually identical apart from the "Ersatzlast" resistor box. I assume that the frame to the right of the Umformer frame is part of the Neptune installation.

I have the parts manual for the Me 262 A model, which has consistant F-numbers with those mentioned by Dufleuve. Interestingly it does not mention an "Umformer" at all, so I suspect it was fed by the U17 of the FuG 16 zy. The Me 262 B had a FuG 125 C variant, which used sligthly different F-numbers. (The F-numbers are rarely consistent anyway, each aircraft manufacturer seemed to use slight variations, same issue with the FuG16zy)

regards,

Funksammler

Well,

I like Piters77 drawing, where both fug120 and 125 are on the same backplane.
Would you have a better scan ? Is it a period document or some post war artist view ?
I unfortunately have no Fug128 manual, still looking for it.
I do have the one for the Fug125 if you're interested (have to scan the copy I have from NASM).

FS,
Any more info on the EiV 125 ? Can't find anything on that one.
Interested in the FuG125 manual, let me know too.

In this B1 config, I do not know where the U17 is located, as the FuG16 lies in front of the radar/radio operator.

Cheers

By the way, the backplates: are those thin steel plates with some surface rust or wood panel with scratches ?

Ah, now I see the F379 and piters77's picture clarifies that the V3 actually looks like the V6, so the mounting frame bottom right is indeed for the V3.

The mounting plates look like wood to me, fairly typical for late war Messerschmitts.

regards,

Thanks to both of you for all the info.
Have now a clearer picture of the mix of Fug120 and 125 boxes on these two panels.
Now I'll have a closer look at the firewall.

Thanks Funksammler and Dufleuve, very curious and interesting discussion, let us continue
Unfortunately, I do not have the book (MMP Me 262 Big Yellow series), but I looked through it, and only this one drawing interested me. Of course, if it's not a problem that will be happy to watch instructions to FuG 125. (piters77ato2dotpl)

Regards,
Piotr

Hello Piotr,
I'll do the scan this week end.

Now, I wonder where the Umformers are located. Need at least a U17 for the Fug16, a U10S or similar for the FuG128 and something for the Fug120 and 125.

Can"t see any mounting for a Umformer in the available pictures.

Cheers
