Searching for Hameg HM604-3 Service Manual

[sprit]

Hi everybody. Wish everyone have a good day.

I have a Hameg model HM604-3. Currently it is faulty in the rear panel. I tried searching the service manual on the internet with no success. Can anyone upload it for me? I have tried contacting R&S support with no success. Thank you so much everyone

Sincerely!

You can try to ask Sky Messtechnik, apparently they've taken over for Hameg. At least that's what R&S support told me. They should also have the leftover stock of replacement parts, but never got back to me when I asked for a certain part.

When I asked their support they gave me this page
https://sky-messtechnik.de/reparaturdienst-service/downloads

If it's not on there then they don't have a clue either
Good luck!

Found the manual for your specific model:

https://elektrotanya.com/hameg_hm604-3_oscilloscope_um.pdf/download.html

And some schematics:

https://www.radiomuseum.org/r/hameg_hm604hm_60.html

Just click on schematics (on the right side of pictures)

The schematics are however for the 604 model. Do not know if it is for your specific model (604-3). But with a bit of luck the board you are having problems with is the same across these models! Could only find this schematics for the 604.

Good luck!
