Where can I get the schematic for a Channel Master cassette recorder model 6305?

I believe that these are badge-engineered Sanyo recorders. Transistorized Japanese consumer electronics are somewhat notorious for having a dearth of service information; hope that you can turn something on this guy.

I'm troubleshooting no volume. In the process a wire from somewhere on the pc broke. It goes to a terminal on the ear phone jack. I first have to reconnect this wire because effectively I may have two volume or no sound problems. If the volume was good in the first place and I broke this wire depending on where it was connected on the ear phone jack it could knock out the volume, right? Any suggestions as how to find out where on the pc this wire goes without a schematic?

The broken wire is either the "hot" audio output lead or the switched lead to the speaker. (The earphone jack has an integrated switch that cuts out the speaker when the earphone is plugged in.) If you have an earphone, plug it in and see if you get sound. If you do, the broken wire is the one that goes to the speaker. If not, it is the one that goes to the audio output transformer secondary.

Check the speaker to see if it has two wires soldered to it. If not, the "empty" terminal is the one your wire goes to.

If no luck there, try to find the audio output transformer on the PC board. There should be a broken-off wire stub in its vicinity coming out of the PC board. You may have to disassemble the unit and use a magnifying glass to find it.

:I plugged in the earphone and got audio. I touched the broken wire to the audio output transformer and the speaker and go no sound. Since I don't have a schematic I just quickly touched the broken wire to various terminals. I got audio at two terminals but it was low volume. I know the voltage is good because I put in new batteries. So it could be anything like a transister right?
