My daughter and I (it's actually hers) will probably work on this over the weekend. I just wanted to let you know that I had a box of dupont wires hanging around, and they fit the socket and connector perfectly, so I'll be able to make this a fully reversible mod by just inserting a switch in the middle of the new wires.

I have a Tascam 414, and I'm wondering if I can do live looping with it if I defeat the erase head just as you have done. <br />Basically I'm wondering if I can continue loops and stack them on top of one another without having to switch to playback. Does disconnecting the erase head fix this at all?

It was filthy on the outside, but the heads and inside were pristine. After a thorough cleaning it's working perfectly! I'm have no need to mod it as I am using it to archive projects from the early '90s. I'm dumping two of the tracks to a DR-40, which I see above you are using as well. It's such a perfect set-up.<br /><br />Did anyone ever send you schematics?

Thanks to your research I was ...Hi, great article ! Thanks to your research I was able to reproduce the same result on my Tascam Portastudio 414 (regular one, not MkII). The thing is, I am also a COMPLETE noob when it comes to circuitry and things like that. I was able to unplug the 8-wire connector, but I don't really like the idea of having it moving around freely in the case, touching something it shouldn't and frying the unit. I was wondering how did you solve this ? Did you tape the connector somewhere safe on the board ? I was thinking of adding a switch between the male and female plugs, so I could switch the erase head on and off, and not having to open the case each time I need to. What do you think of that ?<br /><br />Anyway, thanks a lot for this article !<br />Cheers,<br />Jyb / ZalhietzliJybhttps://www.blogger.com/profile/00749672970030771765noreply@blogger.comtag:blogger.com,1999:blog-1249615655314260587.post-46589480343820220902014-03-22T15:12:26.416-04:002014-03-22T15:12:26.416-04:00hey, with a tape inserted or with the button depre...hey, with a tape inserted or with the button depressed with my finger it does the same thing. with nothing in the deck/pressing the button it does nothing at all. <br /><br />the capstan does spin all the time - when i turn the machine on at first it seems to be winding harder for a second or two and it slows to a constant rate. i'm not able to stop it with my fingers, so i think its pretty strong.<br /><br />as far as motors there seem to be two - the capstan motor and a motor for the reels. there are a number of gears and a few belts to make things move together, but i dont see other sources of movement than those two motors.<br /><br />heres a video: https://www.youtube.com/watch?v=_3TGy8j7tjo&feature=youtu.be<br /><br />i filmed it in portrait mode because i am very smrt. you can see me poke the little button for "tape in" and then off camera press the play button a few times (this is the transport moving up)Anonymoushttps://www.blogger.com/profile/18409209517491339328noreply@blogger.comtag:blogger.com,1999:blog-1249615655314260587.post-56139219622168721282014-03-21T16:54:00.620-04:002014-03-21T16:54:00.620-04:00There's like six motors and actuators in tape ...There's like six motors and actuators in tape transport complex. It's a pretty nice little piece of engineering. I am absolutely a newb when it comes to working with these things, but your theory that it's a malfunctioning sensor sounds pretty good.<br /><br />Just to confirm, the capstan should be spinning all the time...played, stopped, doesn't matter. If the unit is on, the capstan should be spinning. Is yours?<br /><br />Assuming it is, take the tape out and try hitting the play button. As you know, it definitely won't work with no tape in there, but does it "not work" the same way? Or, does it sound/respond differently. If different, then it's probably not the button that detects if the tape is present.<br /><br />Can you take a video of your Portastudio not working and put it on Youtube? I'd love to see the symptoms...Chiphttps://www.blogger.com/profile/10352943033779293161noreply@blogger.comtag:blogger.com,1999:blog-1249615655314260587.post-82079033299037793152014-03-21T16:49:26.658-04:002014-03-21T16:49:26.658-04:00i picked up a tascam portastudio 424 to do the sam...i picked up a tascam portastudio 424 to do the same thing as you but its a little broken...i have the same old MKI as you have in these pictures and I wonder if you know anything about fixing these joints? <br /><br />my problem is that the tape transport doesnt work. when you hit play, it jerks up and then right back down without playing the tape. what's weird is that the fast forward/rewind functions work ok.<br /><br />i've replaced the drive belt and verified that the capstan is spinning freely - i think that motor is OK. at this point i think its either the motor for the reels or simply a sensor or button that is not aligned right. you seem to be the only person with an original 424 cracked open on the internet so I figured it was worth asking here.Anonymoushttps://www.blogger.com/profile/18409209517491339328noreply@blogger.comtag:blogger.com,1999:blog-1249615655314260587.post-69162059129454111372014-03-17T07:42:50.106-04:002014-03-17T07:42:50.106-04:00Cool thanks - well on my machine there is only one...Cool thanks - well on my machine there is only one big fat red wire that goes from the erase head to the circuit board.

It is certainly possible that the erase function is implemented similarly on your UHER 4000 as on my Portastudio, but I don't know.<br /><br />If I were to put switches (or pots) on my Portastudio, I've already found the connector that goes from the main PCB out to the erase head. That's the connector that I show connected and disconnected in my photos. I could imagine cutting into the cabling that goes between the erase head and main PCB and inserting a four switches to selecting "cut" the wires for a given track.<br /><br />You'll notice in my picture of the connector that there are 8 pins...2 for each track. So, if I were introducing switches, I use a double-pole switch so that it "cuts" both wires for a given track.
