I got a Teac E-3 head demagnetizer thrown in with a deck I bought a while back. There were no instructions. How do I use it and know if it works? It makes a buzzing ( kind of like a hair clipper) sound when I switch it on. Is this normal?

Does it have two prongs like pincers out front?

I bought one with my TEAC RTR back in the 70's and was never sure if it worked.

I put tape over the end of the pincers to prevent damage to the heads.

The red light was on so something was happening. :scratch2:

It has a single pivoting "finger" with a plastic cap. No light, just the buzzing sound. Do I move it across the head or hold it there? Should I touch the head? Any tips as to where to get a manual?

I have the E-1 and its the same for both. You move it to within 12in of the head then turn it on than move it slowly to the head move the tip across the heads face 4 or 5 times than slowly move it away till 12in away than turn off.You do this for all the heads and any guides and the capstan.

ps: Make sure the Deck is off.

Royboy,
Teac E-3 is the same as many others, leave the plastic tip on.
You can test if it works using a paperclip first, hold the demag close to the clip and press the ON button, if the demag starts buzzing you have a winner.

Instructions:
Take the tape off the machine and turn the power off.

That is very important otherwise when coming close to the heads, 60 cycle current pulses produced by the demag will look just like 60hz audio signals to the heads and will seriously damage the electronics + VU-meters try to escape the room. :cry:
Sometimes it's also better to take the head-cover off so you can reach properly, it depends what reel to reel model you have.

So turn off the machine first.
Plug the demagnetizer in and 4 feet away from the recorder you push the on button. Move slowly in to the headstack .
Move the demag slowly up and down close to the head, not touching the head, and slowly move away (on button still engaged) at least 3-4 feet away and release the button.
NEVER let go of the on button when close to the head, that will do the opposite and magnetize the heads instead... :sigh:

After you do the playback-head and record-head + tape-lifters if your deck has that,you are done, skip the erase-head.

Congratulations ! :yes:

That pretty much answers my questions. Thank you all.

I've got one more to add although it sounds kind of dumb. When you do this, do you go after all of the heads at once (one after another) or do you have to back off and then go after the next one?

You back off and go after the next one. :)
