    Resoldering wires in transistor radio
    I found an old Channel Master transistor radio (from around 1960) and had it working. However, when I went to clean it (it was filthy), I pulled a wire loose from the circuit board. In the process of getting to the broken wire I pulled several more loose. I resoldered wires I was certain of, and have been holding the others loose because I couldn't quite remember where they went. I've been holding wires together to figure out what goes where, and I managed to get it working through both the speakers and the headphone jack. However, there is a problem: when I turn the volume all the way up, I can only get low volume in the speaker, and when I use the headphones, I can only get it up to a moderate volume. No where near where it was before. What would be the cause of this? Do I just need to solder the wires I've been holding together, or could it be bad soldering? Do I have a wire in the wrong place? Thanks in advance.

    I would suspect wrong connections,
    Be sure you have shiney connections(Not a cold solder joint), adjacent connections not touching each other.
    Model Number?

    I believe it is a 6506. I'm new to soldering, so my connections aren't the best. I'm hoping that if I solder everything maybe the problem will be solved.

    Could maybe just heat back into place, if dirty and it needs to be redone,
    Desoldering Iron would work well to remove the solder from the connection, then with a good soldering pen with "tinned" tip, heat the connection, and feed the solder into the connection, do not heat the solder on the wire.
