1960s? Philco-Ford Portable Compact Cassette Player/Recorder

When you get it running well, you can then say "You've Listened To A Ford Lately"

Well I guess what I meant is that it was the earliest compact cassette recorder I've ever owned.

Anyways, I did recap the unit, but then I had a wire come loose on the circuit board on this unit, a red wire, that I can't figure out where it came from.
I assumed it came from an area near where another red wire had attached to the board that was part of the power switch that turns the power on for the amplifier when you hit the play button, but it didn't seem to do anything when I attached it to there.
I looked up the Sam's for this unit and that didn't even show the wires attached to the board and where they went, and the schematic wasn't much help either because as they didn't have the wires labeled with their respective colors.

I did finally figure out where those two red wires went but now I'm not getting any audio out of the unit (no audio playback and its not recording either) which is weird because I never touched any of the audio portions of the circuitry.

Any ideas as to where I might troubleshoot for audio playback and recording issues?

Red wires USUALLY power from the battery pack to the unit.
You know where one end goes so look in Sams to find where it goes.

I got the red wires straightened out already, its getting power now to the motor and what not, but the audio related circuitry isn't working now, because I'm not getting any audio playback from the tape when I play it, and I'm not getting any audio when I try to record either (the audio level meter doesn't move when I have it in record mode.)

Are you getting power to the amplifier stages?
Did you re-cap the amplifier stages?

I'm not sure if it is or not because when I hit the play button I don't hear anything out of the speaker not even a hissing noise, even if the volume is turned up full bore.

I know one of the red wires I had to trace out on the schematic went to the battery/record meter, and that one when I reattached it started the meter functioning again for the battery meter portion, but the record meter portion doesn't function or respond when I put the tape player into record mode, which is why I said the playback and record functionality of the unit is dead, besides the no audio playback mentioned above.
The other red wire was for the power switch that is part of the Play/FFW/REW/Rec push button asseembly that supplies the power to the motor (and amplifier I assume) when you push play when you are using batteries, and while that wire when I installed it works the motor it doesn't seem to work the amplifier stage for some reason.

I wonder if where I have the red wire for the "power switch" installed currently, is wired up in a way that it powers the motor but not the motor and amplifier stage?

I did recap the amplifier stage, that's how I got into the mess I'm in now with the broken red wire leads that I had to trace out and repair.
