    TEAC 3340 problem

    Sign in to disable this ad
    I can't beleive it. After going on and on about my old reliable 3340 I now have a problem. Channel 4 plays back all previous material but last night when I went to record, it showed normal signal on the VU and the red light lit up but when I played back I got almost no level and could just barely hear what I had done. Like I said, the playback circuit seems fine as all my old stuff sounds great with normal levels. The problem seems to be in the record circuit. The fact that my VU's show level when I'm in source/record mode tells me the inputs are fine. Any ideas?

    The simple and obvious ones are the first thing to check which is the tape itself and the cleanliness of the path.

    Does it reproduce the problem with a different roll of tape - fresh stock?

    Same lack of level off the sync and repro heads?

    Dirty input pot on deck - turn it a few times just in case?

    Dirty sync/repro monitor switch on channel?

    dbx cable link problem/calibration level on dbx unit if any?

    After that, it gets ugly and internal; re-seating cards - intermittent internal wiring harnesses...

    Let us know your findings!

    Good luck, man!

    Cheers!

    Ghost, You won't beleive it.
    This is so weird. Just after I tried 'all the obvious and simple ones' and realized that it was indeed 'internal and ugly', I scored ANOTHER 3340 for $150 CDN. It actually a better unit as my old machine was a A3340S where this is the true 3340. You know .....vari speed, input swithches, function select, etc. I swear it even sounds a bit better. Maybe that's just my joy ringing in my ears. The kicker is that I got an Otari MX5050 8 track with the deal. (with the remote but no cable) The transport won't engage when you press play and the pinch roller has a bit of a bite out of it but everything else seems in pretty good shape. Any ideas about this fix? I'm just gonna enjoy the new 3340 for now but when I get to fixing up the 5050 I'll probably pick your brain....again.

    Congrats on the 3340 score!

    What an incredible deal you got, especially with the Otari thrown in!

    I've got zero experience with Otari repairs but there are a few Otari dudes on this forum so who knows? Maybe one of them will have the magic fix for ya on it?

    What are your plans for your old A3340S?

    Cheers!

    I am going to keep it for now. It was given to me by the bass player in my old band (The Snipetones) I kinda have to give him first choice of refusal. I will probably get it fixed at some point as the heads have a lot of life in them. For now have to settle in and get some recording done. My wife plays for a folk group called Tamarack and they are going to do some pre production stuff here. Also my long awaited (ha ha) solo project is overdue. I just ordered 20 reels of 1/4" from Long and McQuade. It would make my wife very happy if I stopped spending money and started working.........but then there is that Otari and maybe if I.......no, no, I must have strength,LOL.
    If you're ever in the Greater Guelph Area you'll have to stop by.

    BTW I will start a new thread about the OTARI

    That sounds like a plan for sure!

    Only, I have no idea when I'll be up in your area?

    I have a buddy who lives in Totenham and I do get up to his place once or twice a year so who knows? Maybe I'll make a detour one of these days?

    Cheers!

    I'm losing it.

    You can tell I'm pushing 50 and my brain is slowwly dying. My new deck is a 3440, NOT a 3340 but you probably figured that out and were too polite to say. Time for some milk and cookies and then bed.

    Happy Snipeguy

    Hi. I just got a 3340. I seem to be having the same problem you were having. I admit I have not yet tried cleaning/demagnatizing everything and using a brand new tape. If I play a commercially release tape...all is fine. If i record something, the VU meters seem to be accurate...but when i play back what i just recorded, the left channel plays normally But the right channel plays back very quitely. Im hoping this is not something serious.

    In any case, I have a blown light bulb on one of the VU meters. Do you know how to change them? Thanks

    Arrow You gotta clean the head thoroughly with a light but firm scrubbing action,

    with tactile finger pressure applied directly to the head, and repeat a few times, before going forward.

    In other words, don't just swab it lightly with the stick type swab. Get your finger on the swab tip and head surface, and apply a reasonable finger pressure while cleaning.

    Sorry if I repeat myself, but sometimes the cleaning issue is glossed over lightly, and some oxide residues may be tougher than you might think at first.
