Hi everyone
I have an old German Stabo (Multifon Super 7) 2 walkie-talkies.Communication length between 2 of them was too short.So I decided to change all of the old electrical capacitors.

Now between 2 walkie-talkies, there is no connection.I think I might be changed somehow the frequency levels each of them.Is there anyone who have datasheet or device reference guide?
Thanks.
