Another ides when it comes to finding a pre-recorded tape is look at a second hand shop.I was fortunate to find some Herb Alpert and the T J B originals from the mid '60's.
From your experience, what procedure is best to bias a tape on an RTR without having the over bias spec ? Can you provide a step by step procedure - Thanks !
Hi Matt ... great video to explain things without the need of high tech equipment. I recently bough another deck (it's addictive), a GX4000D (I have an enjoy a GX625 too). She (GX4000) has been cleaned up nicely, inspected, lubed and works well but when I recorded some music on both sides of a tape, I can definitely hear bleeding or what I think is known as back-channel playback. It's really pronounced and identifiable as the artist singing in reverse. Can you point me in the direction for proper adjustment? I mean do I only need to adjust the play head or all heads? I'm nervous about adjusting as I've read about the disasters when doing it. I'm also struggling to find a demo video of the procedure. I did figure I might try to make a CD with test tones to use as a source to match tones after I get alignments right and I'm told one can get a pc/Mac/iOS app to simulate an oscilloscope to check the frequency match through the RCA outs? Any help would be appreciated. This started as a desire to get a machine to play record music on my older hifi an relive some youth and has turned into a fun full-time hobby! Thanks for reading...
Hi LM, first, try playing a factory recorded tape to see if you have bleed over. The issue you mentioned could be your record head misaligned, hard to tell. With a factory recorded tape you'll be certain. If there is no bleed over with the factory recorded tape, you record head may be out of alignment.
Great tip, thanks! My experience is that there’s usually some minor bleed over even with properly aligned heads on some of the cheaper 1/4 track machines. Regardless this is a quick and dirty screen. Looks like your shop is busy!
If your machine has two separate heads for side 1 and side 2. You would have to repeat this procedure for each head right, side one get to end fo song check for bleed over from side two adjust if necessary. put deck in reverse get to end of song check for bleed over from side one adjust side 2 head if necessary. Right?
@@biglew1161 Hi Big Lew, most auto reverse units indeed have separate heads for forward and reverse play. These heads have 2 tracks each (Left & Right channels). Follow the guide in the video and you should be able to quickly tell if either head needs adjusting. Take care, Lew
Hi Bigg Matt. I recently picked up a Teac A-2340. The #3 vumeter moves during playback, but not much. The other channels are fine in playback mode. All channels register fine in record mode. What might be a good place to start troubleshooting? Thanks.
I have a Teac X200R that I thought was in great shape. I usually use it at Christmas time. I hadn’t used it in a while but usually “exercise “ it (play tapes w the sound down) just to keep it in shape. I put my favorite holiday tape on a the sound was “ blurry “ in and out . I assumed the heads needed cleaning but they were in good shape. The interesting thing is I hear the blurry sound when I try to record and listen to the monitor from the source. I have no idea where to start. Any suggestions?
What is amazing job u doing , I love that . Interesting. I have a problem happened to me and as per the video u look so smart in this machines . I have reel tape and I play it in Akai650D 4 track , but all VU has no indication at all . So I bought other player Akai2000S ( circuit integrated ) 4 trck also , It played well , Why is not playing in the first one ? There r both 4 track
My rt-701 sometimes has bleeding on pre recorded tapes and sometimes does not. On average what percentage of the rt series need to be re-aligned from the factory setting?
Nerd! Thanks a lot man. Everybody wants to get all crazy with o scopes but this makes too much sense. Thank you thank you thank you!
The Master shares his immense knowledge gracefully, thanks.

Doesn't get much better than that, SBZ
Makes total sense. What's getting me is I'm repairing a blend of A77s that are 4 or 2 track. So I'm at a loss for the 2T models.
@@MikeGervasi This procedure only works on 4 track units
Thanks for a great way to check alignment. Even I understand this!

I've never encountered that scenario.

@@5thcomm Thanks Matt ... I'll try that.... now I have to find a prerecorded tape!!
how about from another machine that I know does not bleed ... at least on itself
Big Matt: That's a great tip. I never thought of that before. I definitely will try it out.
Здравствуйте Мэтт, видео у вас просто на высшем уровне, делайте больше таких видео,,я просто ими наслаждаюсь.
Вы очень добры - спасибо

Great point, JD. You can certainly pick up some faint bleed over on some machines, especially if the tracking is slightly off.
If your machine has two separate heads for side 1 and side 2. You would have to repeat this procedure for each head right, side one get to end fo song check for bleed over from side two adjust if necessary. put deck in reverse get to end of song check for bleed over from side one adjust side 2 head if necessary.

Very helpful info.
Very good contribution brother
Bigg Matt,
Could this also work for a Teac a440?
Certainly
knowledge is power. thanks for the class Teach
nice collection!

Imho it's going to be a bad capacitor or possibly a bad belt. Statistically those two things are going to be at the top of the list
