I changed the main drive belt on a reel to reel stereo tape recorder model no A1340 serial no 3642 there is a small wire arm under the play/ record head platform . I believe its the record switch . the arm is not straight looking at machine the arm is straight from switch and go at a 45 degree angle then turns straight and then angles up about a half inch or less . i need to know how to replace this arm ( switch) back into the the head platform so i can start using this recorder
do u have rhe service manual for this machine if so ca i get a copy ?

The TEAC 3300 made in 1972 is an extremely versatile tape deck, designed for the beginner through simplicity of design, yet built to the high technical requirements demanded by the semi-professionals and experienced audio enthusiasts.
The unit will operate at 7.5 or 15 per second and is available in 2 or 4 track configuration.
Most reel to reel tape recorders have "line out" in the form of RCA phono jacks. These are designed to be connected to an external amplifier. Some unit, however also have an internal amplifier and will output to speaker jacks that should be clearly marked. If your unit has such jacks and you cannot control the sound, your amplifier must be bad. Keep in mind, on most recorders, there are no internal speakers or output amplifier and the volume controls on the front are for recording only.
Problem could be in either the record or playback circuits of unit. Try playing back a tape in another machine to see what the volume is like. If also low then the issue is with the record amp circuits.
Fixing will not be cost effective, however.
It's a 4-head reversable deck where the Forward tracks are arranged across the physical tape surface, front-to-back as follows:
ForwardLeft ReverseRight ForwardRight ReverseLeft
...so it sounds like the Reverse playback heads are engaged at the same time you play Forward, so you would hear those adjacent tracks backward. If you play the tape in the Reverse direction, is the Forward program audible (but backward)?
If so and in otherwise high fidelity, something in the Forward/Reverse head selection may be hosed.
Or, if the out-of-phase tracks are mushy and low volume, the physical tracking of the tape across the heads could be WA-A-A-A-Y bad. That would probably be visible as sideways distortion in the tape path. Shine a high-intensity light on the tape where is passes over the heads, then reverse it while watching where it sets up on the heads. It should be centered on the heads and not change its orientation when reversed. Compare where it tracks in motion with the probable visible wear marks (shiny bars across the heads perpendicular to the travel) where the tape has polished the heads over the years.
Or, the heads are so worn the coils pick up signals from their neighboring tracks.
HAVE YOU TRIED TURNING THE REELS OVER? ON SOME PANASONIC UNITS THE REELS CAN BE PLAYED IN EITHER DIRECTION BUT THE SOUND IS REVERSED IF THE REELS ARE UP SIDE DOWN. TRY TURNING THE REELS OVER AND IT SHOULD STRAIGHTEN OUT YOUR AUDIO PROBLEM AS WELL AS BOOST THE VOLUME
Yes you need to hook it up to an amplifier and speakers through RCA cable on the back. And or you can use headphones if there is a headphone jack? Also make sure there is something recorded on the reel tape in the first place. You can do a test recording of something like a CD from your CD player or record something, then play it back, make sure you turn the record input volume knob up and make the RCA connections on the back of the reel unit and connect to your playback source you want to record. When you playback the reel tape, the db meters should be moving on the front of the reel deck, if they move then you most likely have some sound recorded on the reel tape. If you still can't hear any sound and the db meters are moving, then check all your connections again and volume output knob on the reel deck. Hope this helps?
