Refurbishing my newly acquired A-3340S. Looks like the grease TEAC used to lubricate the pinch roller lifter assembly has hardened up. Will have to remove the capstan/flywheel assembly and a circuit board to get to it. Service manual gives only general instructions for this procedure. There is, however, a helpful video on YouTube about correcting this same factory defect on a different TEAC deck. After I remove the hardened grease I will lubricate the lifter assembly with sewing machine oil. That's the only problem with this machine so far. After I get it going I will look for other issues.

re: A-3340S -

I got mine a few months back and have just had time to look at it.
Squeaked like crazy and found that it was on the tape guide to the immediate right (looking head on) of the left tension arm. (BTW, BIG thank you for the service manual!) It was seized tight, so I used a pair of non-toothed channel-locks to carefully remove the cap.
On removal, going toward the machine, there's the cap, a silver 'roller', then an cylindrical aluminum block that rests against the faceplate. I had to be SUPER careful because the screw that comes from the back of the faceplate has NO RETAINER. There didn't appear to be any felt or bering or anything for the tape to roll on, just metal on metal on metal. Anyone have an exploded diagram of how this unit is supposed to go together? I can't believe tape is just supposed to rub against it. Any chance this is a bolixed repair from someone else?
Thanks for any assistance!

Was looking for an owners manual for a Teac 3340. You had exactly what I needed. Thanks very much!

TEAC 3340 Voltage question

Hi there!

Just bought this unit on Ebay and now I wait for delivery but there is one issue i'd like to clarify before actual item arrives.

I'm from Ukraine and we only have 220V in circuits but this machine is from US so during more than 30 years of exploitation it was set up for 110V.

I've spent pretty much time on reasearch of user/service manuals for device and found out that there IS an option of switching power supply unit to 220V but I still don't know how risky it is to "touch the dust" in such machine, you know.

Also, there is an option of buying power transformer from 220 to 110 and for this I also need to know how much power this machine has in Watts.

So could anyone help me to make a decision - which way is better? Should I really provide some resoldering work or it's more logical to buy a power transformer (and in last case, i need to know a power capacity of the machine)?

Thank you very much for your help, friends! ;)

Recording On 3340S


First time recording.....I am trying to record voice and pre-recorded CD music on my 3340S using 2 channel. I have the CD deck inserted on the back line input for channels 1 and 3 with record buttons on. Then I plug the mic in the front in channel 1. The meters show input on 1 and 3, and I can hear it on headphones....but after recording, playback output for 1 and 3 has music but no voice.

Am I suposed to record voice on rear 3 and 4? If so, I then can't plug in headphones for fron and rear unless I get a Y cable. Or, am I to activate simul-sink for 1 and 3?

Any help on recording this way is appreciated. I also have the Teac mixer but haven't used it.

3440 power cord

It's a two prong, ungrounded, connector. I just purchased a 3440 and think I remember seeing some two element connectors on ebay. Try searching 3440s on ebay if you haven't found one by now. Hopefully, it or they haven't already been sold.
